VIDEO: Better Flow Quantification and Rise of PET Among Trends in Cardiac Nuclear Imaging

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.

He spoke on artificial intelligence (AI) development for medical imaging in sessions at the 2019 American Society of Nuclear Cardiology (ASNC) annual meeting.

VIDEO: New Cardiac Radiotracers in Development

Robert C. Hendel, M.D., explains some of the new cardiac radiotracers in the pipeline that were discussed in sessions at the American Society of Nuclear Cardiology (ASNC) 2019 meeting. 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.

VIDEO: Practical Considerations for Starting a Cardiac PET-CT Program

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.

VIDEO: New Ideas in Addressing Cardiovascular Disease Disparities

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.

CT Angiography (CTA) | August 08, 2019

VIDEO: Example of an Automated CT Cardiac Calcium Scoring Exam

This is an example of an automated calcium scoring software to speed review of coronary artery calcium (CAC) scoring cardiac computed tomography (CT) scans. This advanced visualization software from Ziosoft uses artificial intelligence to segment the coronary vessels, identify valves and the aorta and then color code tag the calcium deposits and quantify the amount of calcified plaque in each vessel. It tallies the score into a table and computes an overall Agatston risk score. This risk score correlates to that patient's risk for a heart attack in the future. The software notes calcium in the heart outside the coronaries in valve leaflets and the aorta, but excludes this data. This type of automation is now offered by most advanced visualization and CT system vendors. This automation can save a large amount of post-processing time and make it easier for hospitals to offer low-cost CAC CT screening programs.

CAC scans can be used to determine if a patient needs to go on statin therapy. An Agatston score of zero means the patient has no risk of coronary disease.

Calcium in arteries is a marker for damage caused by vessel wall inflammation from atherosclerosis. Calcium can form from previously ruptured necrotic, lipid core plaques, also referred to as vulnerable plaques. These are the types of plaque responsible for heart attacks. When the core of these plaques rupture, the blood reacts to the exposed core similar to a wound and begins to clot, forming a thrombus in the vessel, which can block the blood flow. When the vessel heals over time it calcifies, leaving behind an easily identifiable marker on CT imaging.

This example of software was demonstrated on the expo floor at the 2019 Society of Cardiovascular Computed Tomography (SCCT) meeting.
