Ct myocardial perfusion imaging is rapidly becoming an important adjunct to coronary ct angiography for the anatomic and functional assessment of coronary artery disease with a single modality. Existing techniques for ct myocardial perfusion imaging include static techniques, which provide a snapshot of the myocardial blood pool, and dynamic techniques.
Myocardial perfusion imaging or scanning is a nuclear medicine procedure that illustrates the function of the heart muscle. It evaluates many heart conditions, such as coronary artery disease, hypertrophic cardiomyopathy and heart wall motion abnormalities. It can also detect regions of myocardial infarction by showing areas of decreased resting perfusion. The function of the myocardium is also evaluated by calculating the left ventricular ejection fraction of the heart.

The adenoscan vs regadenoson comparative evaluation for myocardial perfusion imaging (advance-mpi) trials, two multi-center, double-blind, phase 3 studies, established the non-inferiority of regadenoson compared to adenosine for the detection of reversible perfusion defects. 6,7 these trials randomized a total of 2,015 patients to sequential (median of 7 days between scans) adenosine-regadenoson mpis vs adenosine-adenosine mpis in a 2:1 ratio.
Myocardial perfusion imaging (mpi) is an important imaging modality in the management of patients with cardiovascular disease. Mpi plays a key role in diagnosing cardiovascular disease, establishing prognosis, assessing the effectiveness of therapy, and evaluating viability.
Myocardial perfusion imaging can also be used to assess functional impairments in the coronary microcirculation, when there are no epicardial lesions. Both myocardial perfusion reserve, and coronary flow reserve were found to be abnormally low in women with microvascular dysfunction, and without significant epicardial stenoses.
Myocardial perfusion imaging (mpi) allows for noninvasive evaluation of coronary artery disease (cad) by detecting flow-limiting disease and providing risk stratification. 1-3 despite a recent decline in popularity likely due to changing physician behavior, it remains the most frequently ordered nuclear medicine exam. 4 it is important for any provider reading nuclear medicine studies to have a firm understanding of mpi acquisition and interpretation.
