ALT Using a practical and time efficient protocol for i.v. glucose loading and insulin administration prior to 18F-FDG injection reduces the metabolic preparation period (MPP) by 61% as compared to oral glucose challenge that affords good-to-excellent image quality in 95% of ischemic cardiomyopathy patients. Overall, the 18F-FDG PET study for viability assessment in ischemic CMP can be performed in about 120 to 140 min. This practical and time efficient protocol should revamp the use of 18F-FDG PET in cardiac viability assessment in clinical practice
