Nuclear Cardiology

Single photon computed tomography (SPECT) and positron emission tomography (PET) molecular imaging are used as primary cardiac imaging modalities to evaluate the function of the heart. It uses radioactive isotopes attached to sugars that are metabolized by cardiomyocytes. This creates an image of the metabolic activity of the heart and shows areas of ischemia or infarct. Other radiotracers can image the heart to diagnosis cardiac amyloidosis and sarcoidosis.

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. 

‘Revolutionary’ new CT scans identify the most common cause of high blood pressure

Primary aldosteronism (PA) is one the single most common causes of hypertension, but identifying patients with PA—and knowing which ones may benefit from a surgical treatment—can be quite challenging.

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.

Cardiologist compensation hits $622K, up 32% from 10 years ago

According to a new analysis from MedAxiom, an American College of Cardiology company, cardiologist compensation has nearly returned to where it was before the COVID-19 pandemic. The detailed report also examined new patient visits, cardiac imaging utilization and much more. 

Comparison of flurpiridaz F-18 PET, SPECT and angiography of the 60-year-old female patients in the Aurora trial. The SPECT scan appeared normal, but flurpiridaz was shown to be more sensitive and showed the ischemia from two blockages in the right coronary artery. The new radiotracer may help expand cardiac PET. #ASNC

Flurpiridaz data shows promise to expand and enhance cardiac PET

The biggest news from the American Society of Nuclear Cardiology (ASNC) 2022 meeting was positive late-breaking data on the phase 3 Aurora trial for the flurpiridaz (F-18) PET radiotracer agent.

PET imaging uncovers a surprising new way COVID-19 affects the heart

A new study in JACC: Cardiovascular Imaging focuses on a potential new side effect of COVID-19, highlighting the continued importance of monitoring these patients going forward.
