title: Tc-99m pyrophosphate myocardial imaging in perimyocarditis.
abstract: A focal or diffuse pattern of Tc-99m pyrophosphate (Tc-99m PPi) myocardial uptake may occur in patients with acute myocardial necrosis from various causes. A recent study has shown intense Tc-99m PPi myocardial uptake in experimental viral perimyocarditis in mice. This report describes a patient with perimyocarditis, with intense, persistent, and generalized myocardial uptake of Tc99m PPi.
