F-FDG PET in Myocardial Viability Assessment: A Practical and Time-Efficient Protocol.

We assessed image quality using a practical and time-efficient protocol for intravenous glucose loading and insulin injection before administration of F-FDG for PET myocardial viability evaluation in patients with ischemic cardiomyopathy (ICM), with and without type 2 diabetes mellitus. The metabolic preparation period (MPP) or optimal cardiac F-FDG uptake was determined from the time of intravenous infusion of 12.5 or 25 g of 50% dextrose to the time of F-FDG injection.
