Indeed, 18F-FDG PET is the gold standard test to identify myocardial hibernation 20 and can be considered when the percent peak radiotracer uptake is between 40 and 60% 21 and the patient is a potential candidate for coronary revascularization. Since the heart is surrounded by tissues of varying densities (eg, bone, lungs, and breast), radionuclide imaging of the thorax results in nonuniform myocardial photon activity due to attenuation from these intervening structures. Most SPECT software packages include quantitative programs that compare patient scans with a normal database, allowing (to some degree) for typical breast attenuation artifact in women. Myocardial perfusion imaging (MPI) refers to the utilization of radiotracers to image regional myocardial perfusion from coronary artery blood flow to the heart muscle.
