Myocardial viability assessment by PET: (82)Rb defect washout does not predict the results of metabolic-perfusion mismatch.

Unlabelled: PET is a sensitive technique for the identification of viable myocardial tissue in patients with coronary disease. Metabolic assessment with (18)F-FDG is considered the gold standard for assessment of viability before surgical revascularization. Prior research has suggested that viability may be assessed with washout of (82)Rb between early and late resting images.
