HCPCS 78452

Myocardial perfusion imaging, tomographic (SPECT) (including attenuation correction, qualitative or quantitative wall motion, ejection fraction by first pass or gated technique, additional quantitation, when performed); multiple studies, at rest and/or stress (exercise or pharmacologic) and/or redistribution and/or rest after redistribution or after a neurohormonal challenge

AI EXPLANATION: A myocardial perfusion scan is a noninvasive nuclear imaging test that evaluates blood flow through the heart muscle. During the study, a small amount of an imaging tracer is introduced into the bloodstream while specialized cameras capture pictures of the heart at rest and following physical exercise or medication that simulates exercise. This allows doctors to examine how well blood circulates to the heart tissue and assess overall heart pumping function.
