In the absence of prior history of myocardial infarction or pathologic Q-waves on the ECG, these patients may have viable, hibernating myocardium, and therefore, should undergo additional testing, such as FDG PET viability imaging (Table1). no Is a low-fat diet really that heart healthy after all? Check with your doc, and you but it would be very unusual at your age. Myocardial metabolic imaging with fluorine-18 fluoro-deoxyglucose (18F-FDG) PET, however, can differentiate them: the metabolically active hypo- perfused region (mismatch between perfusion and metabolic activity) is hibernating, while the meta-bolically inactive hypoperfused region (matched reduced in perfusion and metabolic activity) is scar.

Fixed defects can be associated with normal wall motion (suggesting artifact) or abnormal wall motion (suggesting scar or hibernating myocardium). What does perfusion defect mean?
