Is this good? Learn what happens before, during and after a heart attack occurs. 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. What is the difference between blood flow and perfusion? Defects in perfusion imaging without reversibility is usually interpreted as evidence of prior heart attack related scar. Normal is 50 to 70%. Stress-induced perfusion abnormalities in regions that exhibit normal perfusion at rest are termed reversible perfusion defects, and such regions represent viable, ischemic tissue with blunted coronary blood flow reserve. Its also called a nuclear stress test. Ischemia may be reversible, in which case the affected tissue will recover if blood flow is restored, or it may be irreversible, resulting in tissue death. It is critical to determine whether it is a predominantly reversible defect or only a minimally reversible abnormality. 5 Which is more common anteroapical or anteroseptal mi? The degree of reversibility of a perfusion defect is identified on post-stress images as an area of decreased radiopharmaceutical activity that improves or disappears on rest or redistribution images. Other uncategorized cookies are those that are being analyzed and have not been classified into a category as yet.
