On F-18 FDG PET, {{c1::ischemic}} myocardium shows {{c2::increased}} uptake on FDG PET.
On F-18 FDG PET, {{c1::ischemic}} myocardium shows {{c2::increased}} uptake on FDG PET.
Extra Info
Normal myocardium preferentially metabolizes fatty acids during the fasting state. In contrast, ischemic but viable myocardium has a diminished ability to metabolize fatty acids and must depend on anaerobic metabolism of glucose for energy expenditure. Therefore, ischemic myocardium shows increased uptake on FDG PET. Myocardial scar does not take up FDG.
