No reversible ischemia (lack of blood flow) indicates hypoperfusion (decreased blood flow) at rest or without stress (exercise, etc.) Results from a nuclear stress test: This modality has been used not only to evaluate perfusion, but also to diagnose the etiology of the perfusion defects such as coronary artery ostial anomalies and myocardial scarring [1]. Myocardial perfusion is an imaging test. including myocardial perfusion [1, 2]. This is called a reversible defect. Scarred myocardium from prior infarct will not take up tracer at all and is referred to as a fixed defect..
