Cardiac SPECT

Single photon emission computed tomography (SPECT) is a nuclear imaging modality that uses injected radiotracers to image heart cell metabolism to show functional information on the heart. Cardiac SPECT is used for myocardial perfusion imaging (MPI) and represents the vast majority of nuclear cardiologic imaging exams each year. It is used to determine if a patient has ischemia or an infarct and if revascularization of the coronary arteries will help the patient experiencing chest pain or a heart attack. The FDA has approved four radiotracers for MPI, including thallium-201, 99mTc-Sestamibi, 99mTc-Tetrofosmin, and 99mTc-Teboroxime.

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.

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.  

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.

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

Researchers presented their proposed design of a self-collimating SPECT system at SNMMI 2022.
