VIDEO: Example of Epsilon Strain Imaging Deep Integration With Siemens CVIS

One of the trends in cardiovascular information system (CVIS) and radiology PACS at the Healthcare Information Management Systems Society (HIMSS) 2021 conference was the deeper integration of third-party image analysis software and artificial intelligence (AI) into these systems. This eliminates software sitting on top of the CVIS or PACS, separate logins or needing to us a different screen or manually transferring information from the third-party app in into the final report.

A good example of this was Siemens Healthineers, which demonstrated a deep integration with Epsilon Imaging’s echocardiography strain imaging analysis software. The integration eliminates the need for a separate login to the software, and automated quantification and images are carried over directly into the syngo echo report.

Strain can be used to assess cardiac function more precisely than regular cardiac ultrasound exams. It has grown in its use for cardio-oncology programs, assessing a baseline cardiac function and the. Performing serial exams over the course of a cancer patient’s chemotherapy. Strain has seen growing interest and has been a hot topic the past couple years at the American Society of Echocardiography (ASE) meeting. Interest also has expanded greatly recently with reimbursement now available in the U.S.

Siemens said there also has been increased interest in strain this past year because it can show early indicators of cardiac issues in COVID-19 patients and can be used to help monitor COVID myocarditis patients.

Cardiovascular Ultrasound | August 17, 2021

A new ultrasound imaging technology that may offer novel ways to diagnose and better understand cardiac diseases using dynamic blood flow imaging. This allows imaging of individual blood cells or contrast bubbles as they travel through the heart and vessels, showing detail in how the blood moves and swirls. These motions, including the formation of vortices, may offer new insight into different disease states and allow earlier diagnosis and a understand better when to intervene.

The examples shown in this short video are from Hitachi and GE Healthcare, both of which have highlighted this technology at the American Society of Echocardiography (ASE) annual meetings over the past four years.

Ultrasound vendors use different technology approaches, including vector flow imaging, particle imaging velocimetry and blood speckle tracking. All of them show small lines or arrows to indicate the direction the blood cells or bubbles are traveling, and color codes to indicate velocity. Some vendors offer quantification for some new measures of blood flow, but as of yet, there are no guidelines or standardized indexes as to what these numbers mean.

This technology has been discussed in research sessions at the IEEE and the ASE over the past several years. However, more research is needed to show the prognostic value of the technology. Research to date shows it is possible that the swirling of blood can indicate less efficient flow, which may have implications in the development of heart failure, pulmonary hypertension and advancement of valvular disease. In the coronary arteries, research has shown there may be a connection between sheer stresses and disrupted blood flow in the formation of plaques on artery walls.

Companies that have developed echo blood flow dynamics imaging on their ultrasound systems to date include Hitachi, GE Healthcare, Fujifilm, Mindray and BK Medical.

EP Lab | August 02, 2021

Jass Brooks, vice president of global strategic marketing, Biosense Webster, explains four over-arching electrophysiology (EP) trends at the 2021 Heart Rhythm Society (HRS) meeting. The vendor is working on developing, or has introduced, new technologies in each of these four areas.  She said the key technology trends include:

   • Pulsed field ablation (also called electroporation) as a new way to ablate cardiac tissue without damaging underlying structures like the esophagus. 

   • The introduction of 3D/4D intra-cardiac echo (ICE) imaging to better guide procedures.

   • High-density electromapping systems that create more accurate maps of the electrical activity in the heart and can do so faster than previous generation mapping systems.

   • The introduction of artificial intelligence (AI) into EP systems to speed workflow.

Key among this company's new product introductions at HRS 2021 was the Octaray high-density electro-mapping catheter, which enables faster mapping with a larger number of points. This enables more detailed maps of the heart's electrical activity and may imporve ablation procedure guidance and outcomes. Recent changes to the Carto electro-mapping system now enables integration of this new technology.

Biosense Webster also introduced the Nuvision 4-D intra-cardiac echo (ICE) ultrasound catheter with imaging support from GE Healthcare Vivid Ultra Edition ultrasound systems. This moved ICE beyond 2-D imaging to real-time 3-D and 4-D imaging inside the heart to enable better procedural navigation and visualization of the catheters within in the heart.

Artificial Intelligence | July 01, 2021

Federico Asch, M.D., FASE, director of cardiovascular core labs, cardiovascular imaging, MedStar Health Research Institute, Washington, D.C., was involved in a study that used artificial intelligence (AI) to evaluate echocardiograms to identify COVID-19 patients who were at high risk for complications and mortality. The study also compared human vs. AI variability in reading the stories and found much less variability with the machine reviews. He presented the results from the WASE-COVID Study at the American College of Cardiology (ACC) and American Society of Echocardiography (ASE) 2021 meetings. 

Asch also offers insights about AI applications in echocardiography and how the technology will help improve imaging and reduce the variability in how measurements are made, which will decrease the current level of variability in how exams are performed by human operators. He also explains AI is now available to help guide novice ultrasound users to get optimal cardiac ultrasound images.

Coronavirus (COVID-19) | November 10, 2020

Keith Ellis, M.D., is the director of cardiovascular services and the director of the Chest Pain Center at Houston Methodist Sugar Land Hospital, and has been the director of nuclear cardiology for Diagnostic Cardiology of Houston. He explains how his department has implemented protocols and new technology to mitigate COVID-19 contamination risks and to prevent readmissions. New technologies include the use of telemedicine, CT angiography, and a contrast reduction system in the cath lab to prevent kidney injury that would result in a patient readmission. The hospital also is using techniques to help cut procedure times, including use of radial access in the cath lab and abbreviated nuclear scan protocols to shorten exam times.

He said there can be a lot of cardiovascular involvement in severe COVID patients, ranging from development of myocarditis, STEMI with and without clots, arrhythmias, venous thromboembolism (VTE), and the need for hemodynamic support, including ECMO. He said the most surprising management issue with the COVID patients has been the large amount of VTE, often resulting in deep vein thrombosis and pulmonary embolism (PE). Ellis said this often requires interventional strategies, including the use of Ekos ultrasonic catheter based thrombolysis to break up the clots.

He explains how cardiac CT was used to monitor patients taking icosapent ethyl (Vascepa) showed it showed a 17 percent reversal of low attenuation plaques in the coronary arteries.

Final results from Effect of Icosapent Ethyl on Progression of Coronary Atherosclerosis in Patients with Elevated Triglycerides on Statin Therapy (EVAPORATE) Trial showed a significant reduction in the primary endpoint of icosapent ethyl reducing LAP plaque volume from baseline. Whereas there was a progression of LAP plaque volume in the placebo group. There were significant differences between icosapent ethyl and placebo at study end for secondary endpoints of other types of plaque volume changes, including and sequentially total, total non-calcified, fibrofatty, and fibrous plaque volumes. All regressed in the icosapent ethyl group and progressed in the placebo group, (p<0.01 for all). The only secondary endpoint which did not achieve a significant difference between groups in multivariable modeling was dense calcium (p=0.053).

Cardiac Imaging | August 12, 2020

Advanced visualization company Medis recently purchased Advanced Medical Imaging Development S.r.l. (AMID), which developed software to automatically track and measure strain in echocardiograms. That technology is now being adapted for strain imaging in CT and MRI. Using this imaging data, the software also can noninvasively derive pressure gradient loops and curves, similar to using invasive pulmonary arterial (PA) hemodynamic pressure catheters. This information is useful in monitoring critically ill patients on hemodynamic support and to monitor worsening severity of heart failure. 

The technology was discussed at the 2020 Society of Cardiovascular Computed Tomography (SCCT) virtual meeting. Examples of this technology are presented in this video.

Artificial Intelligence | August 12, 2020

Todd Villines, M.D., FACC, FAHA, MSCCT, explains how artificial intelligence (AI) might be used in the near future to automatically calculate CT calcium scoring and radiomic feature assessments. This was a key take away during the Society of Cardiovascular Computed Tomography (SCCT) 2020 virtual meeting. 

Villines is the Julian Ruffin Beckwith Professor of Medicine, Division of Cardiovascular Medicine, University of Virginia, editor-in-chief of the Journal of Cardiovascular CT (JCCT),  and SCCT past-president.

AI is already commercially used to improve CT image reconstruction to increase the diagnostic quality of the images, especially from low-dose scans. AI is now being applied to automate time-consuming tasks in CT image reads, such as manually calculated calcium scores and automated contouring and quantification of anatomy and function of the heart.

Another area that is seeing a lot of research in in radiomics, where AI is being used to sift through thousands of CT scans to look for subtle imaging traits that may indicate the early development or worsening of disease. These subtle changes may not be evident to radiologists reading the scans, but AI software can identify similarities in patients as a trend and alert researchers to look at that specific trait as a potential imaging biomarker.

Computed Tomography (CT) | August 11, 2020

Todd Villines, M.D., FACC, FAHA, MSCCT, said photon counting CT detectors were a key new technology discussed at the Society of Cardiovascular Computed Tomography (SCCT) 2020 virtual meeting. He said the technology will likely replace conventional CT detectors in the next decade.

These new detectors also can take a single scan and bin the various energies to reconstruct a range of mono-energtic scan renderings similar to dual-energy CT, but on a wider spectrum of kV levels. This spectral aspect of photon counting also allows material decomposition based on the chemical elements that make up various materials in the scan, including calcium and metals that make up stents, orthopedic implants and replacement heart valves. This enables easier, automated removal of metal blooming artifacts and the ability to clearly image inside calcified arteries.

Villines is the Julian Ruffin Beckwith Professor of Medicine, Division of Cardiovascular Medicine, University of Virginia, editor-in-chief of the Journal of Cardiovascular CT (JCCT),  and SCCT past-president.

CT Angiography (CTA) | August 11, 2020

Todd Villines, M.D., FACC, FAHA, MSCCT, explains how coronary plaque assessment will become a new risk assessment tool in cardiac CT. This was a key take away during the Society of Cardiovascular Computed Tomography (SCCT) 2020 virtual meeting in July. He is the Julian Ruffin Beckwith Professor of Medicine, Division of Cardiovascular Medicine, University of Virginia; editor-in-chief of the Journal of Cardiovascular CT (JCCT), and SCCT past-president. 

While basic plaque assessments have been available for several years on CT vendor and third-party advanced visualization software, it lacked automation standardization for what various values meant and clinical evidence it was relevant. However, several speakers in SCCT sessions said that is now changing, with more specific analysis being tested clinically and automation using artificial intelligence. 

Several key opinion leaders in cardiac CT said this new information and automation will likely lead to a revision of the current CAD-RADS scoring system used by radiologists and cardiologists when assessing the coronary event risk of patients. They are calling for the new CAD-RADS 2.0 to include a detailed plaque assessment.

He is the Julian Ruffin Beckwith Professor of Medicine, Division of Cardiovascular Medicine, University of Virginia; editor-in-chief of the Journal of Cardiovascular CT (JCCT), and SCCT past-president. 

Early on in the COVID-19 pandemic in China, CT emerged as a key imaging modality and was found to be able to detect COVID ground glass lesions in the lungs sometimes prior to positive genetic PCR test results. Supporters of CT say the modality offers a way to get detailed anatomical and functional information using a short exam time and limits the exposure of staff to potential or known COVID-19 positive patients.

One area where cardiac CT is seeing a lot of increased his is for the evaluation of thrombus in the left atrial appendage (LAA). This is traditionally done using transesophageal echo (TEE), but it required very close contact with the patient and direct exposure of staff to bodily fluids and potential viral shed from the patient exhaling with each breath.

Jay Mohan, D.O., RPVI, interventional cardiology fellow at William Beaumont Hospital, Royal Oak, Michigan, created this video. It shows other clinicians how he set up his home COVID-19 decontamination area where he changes clothes, shoes and sterilizes before entering his house in order to protect his family. He has been involved with direct care of COVID-19 patients the past two months.

Since the start of the SAR-CoV-2 pandemic, clinicians and first-responders who are in contact with, or possible contact with, COVID-19 patients have developed ways to not bring and viral contamination home with them. This often includes on transition spot in the garage or designed room where they can change out of work clothing and shoes and into new clothing and shoes. Shoes and coats are separated into ones used for home and those dedicated for use at work only. Those who wear and reuse N95 masks also have developed ways to take the mask off by the straps only so they do not touch it and strapping it over a tupperware container that can then be sealed, or stored inside a disposable paper or plastic bag.

Mohan is board certified in cardiology, internal medicine, echocardiography and nuclear cardiology. He also serves as vice president of the Dr. Ramesh Kumar Foundation

Coronavirus (COVID-19) | May 07, 2020

Interview with Geoffrey Rose, M.D., president of Sanger Heart and Vascular Institute with Atrium Health, in Charlotte, North Carolina, and a board member with the American Society of Echocardiography (ASE). He explains the impact of COVID-19 (SARS-CoV-2) on the cardiovascular service line and cardiac imaging. He said the virus has led to use of computed tomography (CT) not only as the frontline cardiovascular imaging modality to evaluate chest pain, but also for COVID-19 pneumonia imaging.

Rose said cardiac ultrasound is still used, but requires full personal protective equipment (PPE) and often abbreviated exams because of the close proximity of the sonographer and patient when performing echocardiograms. This has given rise to using dedicated point-of-care ultrasound (POCUS) systems to answer specific clinical questions quickly. Smart-phone based POCUS systems that use an app and a transducer plugged into the phone enable basic echo exams or evaluation of other parts of the anatomy quickly without the need to immediately sterilize an entire cart-based ultrasound system. These small systems also can be completely enclosed inside a transducer sheath and the phone and single transducer are much easier and faster to wipe down. He said the quality of the exams are not as good as fully enabled echocardiography systems, but it allows for quick assessments of ejection fractions and to triage if the patient needs more advanced imaging if the basic questions cannot be answered.

Since hospitals have shut down now for about two months, postponing normal checkups, and elective exams and procedures, Rose said doctors still need to visit with patients who have chronic conditions. Sanger and Atrium Heath modified its ambulatory electronic medical record (EMR) and is using video conferencing to perform virtual appointments now for the majority of these patients. He said telemedicine was not widely used before COVID-19 in his hospital system, but the pandemic will likely alter the care model for the future, with more telemedicine visits being used even after epidemic is over. He said use of POCUS and CT as frontline cardiac imaging modalities will also likely remain in place after the pandemic because of the efficiencies in care these technologies offer.

Stephen Bloom, M.D., FASNC, director of nonivasive cardiology (cardiac CT, nuclear cardiology and echocardiography) at Midwest Heart and Vascular Associates, Overland Park, Kansas. He is also a member of the American Society of Nuclear Cardiology (ASNC) Board of Directors, explains some of the issues involved and protocols used for cardiac imaging during the COVID-19 pandemic. His discussion includes computed tomography, cardiac ultrasound and nuclear imaging.

Right now, Bloom said it is difficult to test everybody and there is a shortage of masks, gowns and other personal protective equipment (PPE), and the imaging equipment needs to be sanitized each time it is used. He said it is just is not possible to image all the patients who need imaging right now. Hospitals also are trying to limit the number of healthy people people coming into hospitals for routine visits and tests to reduce their potential exposure to the novel coronavirus (COVID-19, SARS-CoV-2) and help containment efforts. 

"The tests should be done, very simply, if it changes the care of the patient. If it doesn't change the care of the patient, and it can be postponed, it should be postponed," Bloom explained. "I would say 80 percent of our cardiac imaging exams have stopped. It has been very dramatic."

Hicham Skali, M.D., a staff cardiologist and member of the Non-invasive Cardiovascular Imaging Program at Brigham and Women’s Hospital (BWH), and at Brigham and Women’s / Massachusetts General Health Care Center at Foxborough, explains the new recommendations from the American Society of Nuclear Cardiology (ASNC) and from imagers in China and Singapore. The ASNC created a best practices document for nuclear cardiology laboratories during the novel coronavirus (COVID-19, SARS-CoV-2) pandemic. The suggestions in the guidelines can ally to any imaging modality, including computed tomography (CT), MRI and ultrasound. 

Skali elaborates on the following points in his discussion, which are specific recommendations in the ASNC and SNMMI COVID-19 guidance document:
   • Rescheduling non-urgent visits
   • Rescheduling elective surgeries and procedures
   • Using separate spaces for patients with known or suspected COVID-19 to prevent spread
   • Ensuring supplies are available
   • Promoting use of telehealth
   • Screen staff, patients and visitors before they enter the department
   • Minimize non-essential visitors into the department
   • Record symptoms at the start of the shift
   • Use personal protective equipment (PPE)for healthcare personnel
   • If available, use PPE for patients due to concern of asymptomatic transmission of COVID-19
   • Maintain strict hand hygiene
   • Maintain 6 feet distance in all patient/staff interactions when possible
   • Work remotely whenever feasible, especially with ready studies
   • Rotating staff schedules for on-site and off-site work
   • Use of rest only studies if possible
   • Use of half-time SPECT to speed exam times
   • Use of PET if available to speed exam times

Skali served as the moderator in for the ASNC on demand webinar COVID-19 Preparedness for Nuclear Cardiology Labs: Insights from the US, China and Singapore.

FFR Technologies | March 26, 2020

James Udelson, M.D., chief of the division of cardiology, Tufts Medical Center, explains how cardiac computed tomography (CT) scans are being used to create image-derived fractional flow reserve (FFR) values to determine if a coronary lesion is flow limiting. The FFR-CT can help determine if the patient needs a stent, or if the disease can be treated with medication. Tufts uses FFR-CT evaluations on non-emergency chest pain patients to reduce the need for diagnostic catheterizations.

Coronavirus (COVID-19) | March 20, 2020

An interview with Ehtisham Mahmud, M.D., FSCAI, chief, Division of Cardiovascular Medicine, executive director of medicine, Cardiovascular Institute, director of  interventional cardiology and cardiac cath lab at UC San Diego Medical Center, and president of the Society for Cardiovascular Angiography and Interventions (SCAI). He explains the how cardiology departments in the U.S. are now postponing cardiovascular procedures due to novel coronavirus (COVID-19, SARS-CoV-2) containment efforts and new guidelines from Medicare calling for delay of all elective procedures in the country. 

Mahmud explains how patients are being prioritized, with acute myocardial infarction patients or others with acute, life-threatening conditions, or at high risk for a near term hospital admission, will still receive cardiac catheterizations, cardiovascular surgery or structural heart procedures for MitraClip and transcatheter aortic replacement (TAVR) under certain circumstances. All other procedures are being postponed until further notice based in the spread and infection rates of COVID-19. He said most hospitals, including his own, are moving to telehealth visits via phone or online to continue clinic work with patients, including those with chronic conditions such as heart failure.

The Centers for Medicare and Medicaid Services (CMS) announced March 18, 2020, that all elective surgeries, and non-essential medical, surgical and dental procedures should be delayed during the coronavirus outbreak. This move is three-fold. 
   1. It is to help with containment efforts by reducing patient and family travel to hospitals, which are at the center of the COVID-19 outbreak. 
   2. Delaying procedures will help preserve and inventory of personal protective equipment (PPE), hospital beds and ventilators and other medical supplies. 
   3. With the start of social distancing and the shut down of all large gatherings, this has severely impacted blood drives and other blood donations, so the nation's blood banks have severely limited supplies.

“The reality is clear and the stakes are high — we need to preserve personal protective equipment for those on the front lines of this fight,” said CMS Administrator Seema Verma.

This will not only preserve equipment but also free up the healthcare workforce to care for the patients who are most in need. Additionally, as states and the nation as a whole work toward limiting the spread of COVID-19, healthcare providers should encourage patients to remain home, unless there is an emergency, to protect others while also limiting their exposure to the virus.

Coronavirus (COVID-19) | March 17, 2020

Interview with Mike Stone, M.D., an emergency physician at Northwest Acute Care Specialists in Portland, Ore., director of point of care ultrasound education at Butterfly Network Inc., and and former chief of the division of emergency ultrasound at Brigham and Women's Hospital, Boston. He explains what clinicians look for in lung ultrasound to evaluate patients for plural wall thickening and areas of congestion inside the lung typical of pneumonia and seen in patients with novel coronavirus (COVID-19, also referred to clinically as SARS-COV-2). 

Small hand-held ultrasound systems may offer advantages over X-ray or computed tomography (CT), because the entire system can be contained inside a protective sheath, making it easier to disinfect the device rather than an entire imaging room. Point of care ultrasound (POCUS) systems also allow triage of patients in tents or other areas outside of the hospital where other imaging modalities are not available. 

Stone shares examples of COVID-19 ultrasound images from Butterfly Network POCUS system technology, which turns an iPhone into an FDA-cleared ultrasound device for multiple POCUS exam types. It is the first POCUS system reported to be used for triage and monitoring COVID-19 patients.

Magnetic Resonance Imaging (MRI) | January 06, 2020

Karen Ordovas, M.D., MAS, professor of radiology and cardiology at the University of California San Francisco (UCFS) School of Medicine and a Society of Cardiac Magnetic Resonance (SCMR) board member, explains how cardiac MRI can help in women's heart disease and to better define complex congenital heart anatomy. She spoke at the 2019 Radiological Society of North America (RSNA) meeting. 

She specializes in cardiac and pulmonary imaging, and has particular expertise in using CT and MRI techniques in cardiovascular imaging and the differences of presentation in imaging between male and female cardiac patients. Ordovas is helping advance education around heart disease in women and bring great awareness of quality tools to diagnose heart disease and how heart MRI can help. She also is heavily involved in the use of heart MRIs for pregnant women, since there is no radiation,  and patients with congenital heart disease where detailed imaging of the complex anatomy is required.

The use of cardiac MRI in congenital heart disease is common in serial imaging of patients with Tetralogy of Fallot (TOF), one of the most common congenital heart diseases for which patients are referred for post-operative magnetic resonance (MR) imaging evaluation. In the past few decades, surgery has proved successful, but most patients require repeat imaging throughout their lives and MRI can offer more detailed soft tissue imaging without the use of radiation.

Magnetic Resonance Imaging (MRI) | December 20, 2019

James Carr, M.D., chair of the Department of Radiology, Northwestern University, and incoming 2020 President of the Society of Cardiac Magnetic Resonance (SCMR), explains why MRI is an ideal cardiac imaging modality, at the 2019 Radiological Society of North America (RSNA) meeting.

Heart MRI offers advantages over computed tomography (CT) and echocardiography because of its excellent soft tissue delineation and its ability to offer information beyond anatomical imaging, such as perfusion, morphology and metabolism. MRI can be technically challenging and the exams requiring a long time, but recent advances have helped cur cardiac imaging times down significantly. Automation and artificial intelligence (AI) also is making post-processing and quantification mush faster, brining it closer to the time it takes to scan and post-process CT imaging.

Northwestern is was one of the early adopters of cardiovascular MRI. Carr said heart MRI was not common in regular clinical use until the past decade at some luminary centers. In 2005, Carr was given the opportunity to develop a clinical cardiac MRI program at Northwestern.
 
He said MRI scanners have improved, and now much faster than a decade ago. They are also more optimized for cardiac imaging. While heart MRI is well known in large hospital centers, Carr said it still needs to develop and expand to community hospitals and rural hospitals outside major population centers. 

Artificial intelligence is playing a significant role in cardiac MRI automation of speeding workflow and quantification. Carr said these technologies will become mainstream in the next few years. AI also will play an increasing role in risk prediction based on new image analysis algorithms in development.

Radiation Dose Management | December 19, 2019

 

Mahadevappa Mahesh, Ph.D., chief of medical physicist and professor of radiology and medical physics, Johns Hopkins University, Baltimore, treasurer of the American Association of Physicists in Medicine (AAPM),a board member of the American College of Radiology (ACR), presented a late-breaking study on how medical imaging radiation dose has started to drop over the past decade. He is the co-chair of the National Council on Radiation Protection and Measures Report (NCRP), and presented the most recent NCRP data analysis at the 2019 Radiological Society of North America (RSNA) meeting.

The new NCRP 184 report covers the period between 2006 and 2016, the period of the most current CMS data. It shows a decrease of about 20 percent in the radiation dose the U.S. population receives from medical imaging, compared to the NCRP 160 that covered the period of up to 2006.

Key findings of the study include:

   • CT dose dropped about 6 percent, despite a 20 percent increase CT scans since 2006;

   • Drop of more than 50 percent for nuclear imaging scans, mainly due to fewer procedures begin performed;

   • A 15-20 percent decrease across X-ray imaging modalities.

Mahesh says this shows the impact of using "as low as reasonably achievable" (ALARA) principals, new dose guidelines outlined jointly by numerous medical societies, and dose reduction initiatives like Image Wisely, Image Gently, and the American College of radiology (ACR) Dose Index Registry.

He said there was growing concern a decade ago when the last council report was published, which show a steep increase in radiation dose. This was mainly due to a rapid increase in the use of computed tomography (CT) and other types of X-ray based and nuclear radiotracer medical imaging. This prompted the ACR top create the Image Wisely program and push for the use of more thoughtful imaging doses based on patient size, using the "as low as reasonably achievable” (ALARA) principle. While CT dose was lowered, he said the biggest decline was in nuclear imaging.

Nuclear Imaging | November 07, 2019

Rob Beanlands, M.D., FASNC, 2019 American Society of Nuclear Cardiology (ASNC) president, shares a couple trends he sees in cardiac nuclear imaging. He is the Vered Chair and division head of cardiology and director of the National Cardiac PET Centre at the University of Ottawa Heart Institute, Canada.

He said overall trends he sees in nuclear cardiology include the use of better myocardial reserve quantification so it is clear whether revascularization would help patients. Beanlands also said there is increasing interest in positron emission tomography (PET) imaging because of its superior image quality and increasing access to PET radiotracers. New tracers on the horizon will also increase the image quality and flexibility of PET to accommodate exercise stress.

Hendel is a professor of medicine and radiology and the Sidney W. And Marilyn S. Lassen Chair in Cardiovascular Medicine, Tulane University. He also serves as the chief of the section of cardiology and director of the Tulane University Heart and Vascular Institute. 

He outlined three new radiotracers that may impact cardiac imaging:

   • Flurpiridaz F-18 PET perfusion agent that offers high quality images and can be used with exercise stress;

   • MIBG imaging to help better assess heart failure classes and if patients may need an ICD;

   • New F-18 agents to image cardiac amyloidosis; and

   • Nuclear agents to enable annexin imaging, allowing direct vsualization of myocardial apoptotic cells.

 

PET-CT | October 30, 2019

Rupa Sanghani, M.D., FASNC, associate professor, Rush Medical College, director of nuclear cardiology and stress laboratory, Rush University Medical Center, and associate director, Rush Heart Center for Women, explains how to create a high-volume cardiac positron emission tomography (PET) imaging program. She spoke on this topic at the 2019 meeting of the American Society Nuclear Cardiology (ASNC) and led a tour for attendees of the PET-CT system at Rush, which was located close to the conference. 

Sanghani said the advantages of PET myocardial perfusion imaging include faster exam times and allowing additional information from coronary reserve flow assessments to better understand if revascularization will help a patient's heart recover. The 16-slice CT scanner is used not only to attenuate the PET images, but to perform a CT calcium scoring exam to assess the patient's risk for future cardiovascular events. The Rubidium-82 radiotracer used for PET exams only has a 75 second half life, so it can help increase the number of exams a center is able to perform each day. At higher volume centers, PET is optimized to handle all the patients who require pharmacological stress exams. 

In the video, Sanghani  outlines what Rush did to design its room, covers basics on training, what to look for in a scanner and other considerations when creating a PET program.

Cardiac Diagnostics | October 29, 2019

Clyde Yancy, M.D., MSc, cardiology chief and vice dean for diversity and inclusion at Northwestern University, Feinberg School of Medicine, was a keynote speaker at the 2019 American Society of Nuclear Cardiology (ASNC) annual meeting. He said the traditional biases of seeing a patient and automatically making clinical assumptions because they are a certain race or gender are obsolete. For example, he said not all black patients have hypertension. Yancy added that genetics, especially with racial intermarriage over the past several generations, no longer predisposes patients to what is typically assumed for certain ethnic or racial backgrounds.

Yancy also said new research is showing how diet plays a major role in patient health and disease progression for things previously thought to be based on genetics. This includes the people who live in "food deserts" in urban areas where there are no sources of fresh food and vegetables, so they consume large amounts of packaged and processed foods that contain high levels of salt, phosphates and preservatives. He said these chemicals and diet may be the root cause of hypertension and diabetes in black populations in low income areas, rather than genetics as previously thought.
