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.

Heart inflammation remains 2 months later in some patients with COVID-19 vaccine-related myocarditis

A team of cardiologists and radiologists collaborated on the study, using advanced imaging to take a closer look at the long-term impact of vaccination. 

ASNC 2023 president calls for nuclear cardiology to embrace new technology

American Society of Nuclear Cardiology (ASNC) 2023 President Mouaz H. Al-Mallah, MD, said the subspecialty needs to up its game with new technology.

A study published this week in the Journal of the American College of Cardiology (JACC): Cardiovascular Imaging shows artificial intelligence (AI) algorithms can more rapidly and objectively determine calcium scores in computed tomographic (CT) and positron emission tomographic (PET) images than physicians.[1] The AI also performed well when the images were obtained from very-low-radiation CT attenuation scans. https://doi.org/10.1016/j.jcmg.2022.06.006

Artificial intelligence can objectively determine cardiac calcium scores faster than doctors

A new study shows artificial intelligence (AI) algorithms can more rapidly and objectively determine calcium scores in CT and PET/CT images than physicians.

This latest shortage involves dobutamine, an injectable medication often prescribed for advanced heart failure and cardiogenic shock. It is also a central component of dobutamine stress echocardiography (DSE), a test used to evaluate patients with severe aortic stenosis.

A new supply issue hits cardiology: 5 recommendations for cardiologists during the dobutamine shortage

The shortage could lead to significant issues for cardiologists. The American College of Cardiology provided some words of wisdom on the ongoing issue.

‘Image of the Year’ highlights the predictive power of a new PET imaging agent

The Society of Nuclear Medicine and Molecular Imaging has chosen its 2022 Image of the Year, and it’s one that is sure to interest anyone in the field of cardiac imaging.

Advnaces in nuclear cardiac imaging include the use of PET, quantitative coronary flow reserve and the additional CT ro SPECT and PERT scans. #ASNC
