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.

Justin Trivax, M.D., an interventional cardiologist who works with long-COVID patients at Beaumont Hospital, explains some of the common symptoms and their prevalence in the Beaumont long-COVID clinic.
COVID long hauler syndrome is no longer seen as a big mystery because large numbers of these patients have been seen and treated. The bottom line is that while long-hauler symptoms are an issue for patients, they do not appear to be life-threatening and the big fear of large numbers of new heart failure patients post infection has not materialized.
"Interestingly, the patients do get better. It is a slow process, but by the one-year point we do see improvement in patients with this prolonged syndrome," reassured Trivax.
Many of the patients Trivax has seen only had a mild case of COVID, but presenting months later with cardiac issues. Trivax said these patients often test troponin positive. The question as to what is causing this often results in a cardiac MRI.
"There are also patients who had very mild symptoms [during their COVID infection] and those patients don't have a major event, however, they may have those prolonged symptoms," Trivax said. "We see this in the MRI studies that have been performed. But, what these abnormal cardiac MRIs really mean, we don't quite know. We don't have any long-term data for these COVID patients."

Aaron Baggish, M.D., director of the cardiovascular performance program, Mass General Hospital, has been involved in the care of cardiac COVID-19 long-hauler patients and monitoring athletes recovering from COVID the past two years.
He spoke to DAIC a year ago in late 2020 about the beginning of the Mass General monitoring of long-COVID patients and he shares what they have learned over the past year. He said the common long-term issues include arrhythmias, brain fog and other issues. Baggish also explains what they do to evaluate post-COVID infection patients with complaints or odd presentations weeks or months after their acute phase of infection ended.

Orlando Simonetti, Ph.D., professor, cardiovascular medicine, worked with Siemens to help develop a new, lower-field magnetic resonance imaging (MRI) system, the Magnetom Free.Max. It can scan patients that previously may have been contraindicated because of implantable medical devices. The first system installed in the U.S. is at The Ohio State University Wexner Medical Center. It has a much lower magnetic field and a larger patient opening, removing barriers to MRI imaging for many patients.
Simonetti and his colleagues developed new techniques to boost the signal-to-noise ratio in MRI machines, which allowed the creation of a machine with a lower magnetic field strength that still enables high quality images.
The system gained FDA clearance in July 2021 and was featured by Siemens at the Radiological Society of North America (RSNA) 2021 meeting.
The interview and footage was provided by The Ohio University State University Wexner Medical Center.

Here are two examples of artificial intelligence (AI) driven pulmonary embolism (PE) response team apps featured by vendors Aidoc and Viz.AI at the 2021 Radiological Society of North America (RSNA) 2021 meeting.
The AI scans computed tomography (CT) image datasets as they came off the imaging system and looked for evidence of PE. If detected by the algorithm, it immediately sends an alert to the stroke care team members via smartphone messaging. This is done before the images are even loaded into the PACS. The radiologist on the team can use a link on the app to open the CT dataset and has basic tools for scrolling, windowing and leveling to determine if there is a PE and the severity. The team can then use the app to send messages, access patient information, imaging and reports. This enabled them all to be on the same page and can communicate quickly via mobile devices, rather than being required to use dedicated workstations in the hospital.
Both vendors showed similar apps for stroke at RSNA 2019. That idea for rapid alerts, diagnosis and communications for acute care teams has now expanded to PE and also for aortic dissection and abdominal aortic aneurysms (AAA). AI.Viz and Aidoc are looking at expanding this type of technology for other acute care team rolls, including heart failure response.

Jean Jeudy, M.D., professor of radiology and vice chair of informatics at the University of Maryland School of Medicine, presented a late-breaking study at the 2021 Radiological Society of North America (RSNA) meeting on COVID-19 linked myocarditis in college athletes.
A small but significant percentage of college athletes with COVID-19 develop myocarditis, a potentially dangerous inflammation of the heart muscle, that can only be seen on cardiac MRI, according to the study Jeudy presented. Myocarditis, which typically occurs as a result of a bacterial or viral infection, can affect the heart’s rhythm and ability to pump and often leaves behind lasting damage in the form of scarring to the heart muscle. It has been linked to as many as 20% of sudden deaths in young athletes. The COVID-19 pandemic raised concerns over an increased incidence of the condition in student-athletes.
For the new study, clinicians at schools in the highly competitive Big Ten athletic conference collaborated to collect data on the frequency of myocarditis in student-athletes recovering from COVID-19 infection. Conference officials had required all athletes who had COVID-19 to get a series of cardiac tests before returning to play, providing a unique opportunity for researchers to collect data on the athletes’ cardiac status.
Jeudy serves as the cardiac MRI core leader for the Big Ten Cardiac Registry. This registry oversaw the collection of all the data from the individual schools of the Big Ten conference. He reviewed the results of 1,597 cardiac MRI exams collected at the 13 participating schools.
Thirty-seven of the athletes, or 2.3%, were diagnosed with COVID-19 myocarditis, a percentage on par with the incidence of myocarditis in the general population. However, an alarmingly high proportion of the myocarditis cases were found in athletes with no clinical symptoms. Twenty of the patients with COVID-19 myocarditis (54%) had neither cardiac symptoms nor cardiac testing abnormalities. Only cardiac MRI identified the problem.

The vendor Radiaction introduced a new type of scatter radiation protection shielding system that mounts to the angiography system in the cath lab. It was shown for the first time at the 2021 Radiological Society of North America (RSNA) annual meeting.
The system uses a motorized series of tungsten-polymer radiation shield plates that extend down from the detector, and up from the X-ray source, to the patient and bottom of the table. This greatly reduces scatter radiation in the lab, by as much as 92% according to the company's research.
The shields are deployed using a table-side controller. The shield has sensors to stop extending when it comes close to the patient or the table. The shield can be partly pulled back to enable panning the table. The company said the shield can be mounted on existing angiography C-arms.
It has CE mark and is installed clinically in two cath labs in Israel. The company hopes to submit for U.S. FDA review in 2022.

Kate Hanneman, M.D., MPH FRCPC, director of cardiac imaging research JDMI, and the medical imaging site director at Toronto General Hospital, Women’s College Hospital, was an author on a recent overview of cardiac MRI assessments of non-ischemic myocardial inflammation caused by the COVID-19 vaccine. She presented this study and other related data at the 2021 Radiological Society of North America (RSNA) meeting.
The rare side effect from the COVID vaccine is seen mainly in young men between ages 12-29. It appears to resolve on its own after a couple days, but longer term monitoring is needed to show if there is any lasting cardiac damage. A small number of single cases with follow up MRI imaging so far have not shown long term damage.
Hanneman noted the incidence of vaccine-related myocarditis is very rare and people have a much high probability of getting much more serious COVID-viral myocarditis is they are not vaccinated. She said so the risk-vs-benefit analysis currently shows it is better to get vaccinated to prevent or lessen the effects of COVID.

The shields are deployed using a table-side controller. The shield has sensors to stop extending when it comes close to the patient or the table. The shield can be partly pulled back to enable panning the table. The company said the shield can be mounted on existing angiography C-arms.
It has CE mark and is installed clinically in two cath labs in Israel. The company hopes to submit for U.S. FDA review in 2022.

Kate Hanneman, M.D., MPH FRCPC, director of cardiac imaging research JDMI, and the medical imaging site director at Toronto General Hospital, Women’s College Hospital, was an author on a recent overview of cardiac MRI assessments of non-ischemic myocardial inflammation caused by the COVID-19 vaccine. She presented this study and other related data at the 2021 Radiological Society of North America (RSNA) meeting.
The rare side effect from the COVID vaccine is seen mainly in young men between ages 12-29. It appears to resolve on its own after a couple days, but longer term monitoring is needed to show if there is any lasting cardiac damage. A small number of single cases with follow up MRI imaging so far have not shown long term damage.
Hanneman noted the incidence of vaccine-related myocarditis is very rare and people have a much high probability of getting much more serious COVID-viral myocarditis is they are not vaccinated. She said so the risk-vs-benefit analysis currently shows it is better to get vaccinated to prevent or lessen the effects of COVID.

Here are two examples of artificial intelligence (AI) driven pulmonary embolism (PE) response team apps featured by vendors Aidoc and Viz.AI at the 2021 Radiological Society of North America (RSNA) 2021 meeting.
The AI scans computed tomography (CT) image datasets as they came off the imaging system and looked for evidence of PE. If detected by the algorithm, it immediately sends an alert to the stroke care team members via smartphone messaging. This is done before the images are even loaded into the PACS. The radiologist on the team can use a link on the app to open the CT dataset and has basic tools for scrolling, windowing and leveling to determine if there is a PE and the severity. The team can then use the app to send messages, access patient information, imaging and reports. This enabled them all to be on the same page and can communicate quickly via mobile devices, rather than being required to use dedicated workstations in the hospital.
Both vendors showed similar apps for stroke at RSNA 2019. That idea for rapid alerts, diagnosis and communications for acute care teams has now expanded to PE and also for aortic dissection and abdominal aortic aneurysms (AAA). AI.Viz and Aidoc are looking at expanding this type of technology for other acute care team rolls, including heart failure response.

Jean Jeudy, M.D., professor of radiology and vice chair of informatics at the University of Maryland School of Medicine, presented a late-breaking study at the 2021 Radiological Society of North America (RSNA) meeting on COVID-19 linked myocarditis in college athletes.
A small but significant percentage of college athletes with COVID-19 develop myocarditis, a potentially dangerous inflammation of the heart muscle, that can only be seen on cardiac MRI, according to the study Jeudy presented. Myocarditis, which typically occurs as a result of a bacterial or viral infection, can affect the heart’s rhythm and ability to pump and often leaves behind lasting damage in the form of scarring to the heart muscle. It has been linked to as many as 20% of sudden deaths in young athletes. The COVID-19 pandemic raised concerns over an increased incidence of the condition in student-athletes.
For the new study, clinicians at schools in the highly competitive Big Ten athletic conference collaborated to collect data on the frequency of myocarditis in student-athletes recovering from COVID-19 infection. Conference officials had required all athletes who had COVID-19 to get a series of cardiac tests before returning to play, providing a unique opportunity for researchers to collect data on the athletes’ cardiac status.
Jeudy serves as the cardiac MRI core leader for the Big Ten Cardiac Registry. This registry oversaw the collection of all the data from the individual schools of the Big Ten conference. He reviewed the results of 1,597 cardiac MRI exams collected at the 13 participating schools.
Thirty-seven of the athletes, or 2.3%, were diagnosed with COVID-19 myocarditis, a percentage on par with the incidence of myocarditis in the general population. However, an alarmingly high proportion of the myocarditis cases were found in athletes with no clinical symptoms. Twenty of the patients with COVID-19 myocarditis (54%) had neither cardiac symptoms nor cardiac testing abnormalities. Only cardiac MRI identified the problem.
