Cardiac PET

Cardiac positron emission tomography (PET) is a nuclear imaging modality that can show heart cell metabolism that reveals areas of ischemia or infarct where this low or no blood flow due to coronary artery disease and myocardial infarction. PET can help determine in if areas of the heart effected by a heart attack can be reversed through revascularization. PET can also offer additional information on the patient's condition with myocardial flow reserve (MFR) information. Cardiac PET uses a rubidium (Rb-82) radiotracer injection, which only has a half life of 75 seconds, which greatly speeds scan times compared to traditional cardiac SPECT imaging.

Numerous advances in cardiac nuclear imaging led American Society of Nuclear Cardiology (ASNC) President-elect Panithaya Chareonthaitawee, MD, to predict "We are on the edge of a new journey in nuclear cardiology, and the opportunities before us are just as vast as they are exciting and promising."

FDA sees potential in new PET imaging agent for cardiac amyloidosis

Early evidence suggests a new PET imaging agent from California-based Attralus can help evaluate all varieties of systemic cardiac amyloidosis. It has now been granted the FDA's breakthrough therapy designation. 

Video interview with Tim Bateman, MD, co-director, cardiovascular radiologic imaging program, Saint Luke's Mid America Heart Institute and an American Society of Nuclear Cardiology (ASNC) past-president, explaining the role of SPECT into the future as PET becomes more popular. A new look at PET vs SPECT.

SPECT still has an important role to play in nuclear cardiology

"I see, at least for the next decade, this being a SPECT and PET world, not one or the other," explained Tim Bateman, MD.

DOJ targets former imaging executive with new complaint over alleged kickback scheme

Back in October, a mobile cardiac imaging provider and its CEO agreed to pay $85 million to settle allegations they had participated in a kickback scheme. This latest DOJ complaint focuses on a former executive not named in that initial settlement.

Cardiologists at heart of alleged kickback scheme—imaging provider, CEO to pay $85M to settle

The allegations revolve around payments referring cardiologists received to supervise PET scans from March 2014 to May 2023.

Timothy Bateman, MD, co-director, cardiovascular radiologic imaging program, Saint Luke's Mid America Heart Institute, professor of medicine at the University of Missouri-Kansas City School of Medicine, and an ASNC past-president, is one of the authors on the AURORA study. He spoke with Cardiovascular Business about the study and what it is like to work with flurpiridaz.

Flurpiridaz will have a major impact on cardiac PET and nuclear imaging

The new radiotracer flurpiridaz is poised to make a major impact on nuclear cardiology. Timothy Bateman, MD, co-director of the cardiovascular radiologic imaging program at Saint Luke's Mid America Heart Institute, shared details on the tracer in a new interview.
