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. 

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.

Lower doses, faster acquisitions: Experts share how to improve PET scans for peds

This week in AJR, experts shared how they were able to reduce FDG PET scan acquisition times by 33%, thus reducing the amount of total radiation exposure to more vulnerable pediatric patients.

The ASNC is one of several medical imaging societies asking Congress to repeal the appropriate use criteria (AUC) criteria mandate. They say it poses issues for clinicians and is becoming outdated by changes in CMS payment systems. The AUC requirements call for documentation using CVMS authorized software in order to show advanced imaging such as nuclear and CT is justified, or else Medicare payments might be withheld.
