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.

SNMMI backs updated ASNC guidelines on SPECT MPI

New 2018 guidelines for myocardial perfusion imaging (MPI) protocols on conventional and novel single photon emission computed tomography (SPECT) for nuclear cardiology practitioners has received praise from the Society for Nuclear Medicine and Molecular Imaging (SNMMI).
