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. 

Researchers have designed a new cardiac SPECT imaging system that could potentially deliver images much faster than current models. The team presented its findings at the annual meeting of the Society of Nuclear Medicine and Molecular Imaging (SNMMI), SNMMI 2022. #SNMMI22 #snmmi #SNMMI2022

The need for speed: New-look cardiac SPECT imaging system could be up to 100 times faster than current models

New multi-society recommendations highlight role of non-invasive imaging in evaluating coronary artery disease

A new, multi-society document, "Non-Invasive Imaging in Coronary Syndromes," focuses on how multiple imaging techniques can evaluate different aspects of coronary artery disease (CAD), all without the need for invasive angiograms.

Eleven medical societies have signed on to a consensus statement aimed at standardizing imaging for suspected cardiovascular infections.

Kate Hanneman, MD, explains why many vendors and hospitals want to lower radiology's impact on the environment. "Taking steps to reduce the carbon footprint in healthcare isn’t just an opportunity," she said. "It’s also a responsibility."
