HCPCS 78492

Myocardial imaging, positron emission tomography (PET), perfusion study (including ventricular wall motion[s] and/or ejection fraction[s], when performed); multiple studies at rest and/or stress (exercise or pharmacologic)

AI EXPLANATION: A myocardial PET scan is an advanced imaging test that evaluates blood flow to the heart muscle. A small amount of a radioactive tracer is administered, allowing a specialized scanner to produce detailed pictures showing how well oxygen-rich blood reaches all parts of the heart. The examination typically includes multiple scans performed both while resting and during physical or medication-induced stress to assess heart muscle health and pumping performance.
