Here PET, in conjunction with CT,1 has been an important tool in the management of oncology patients, accounting for 86% of PET scans by 2016,2 PET with attenuation and motion correction has significant potential for future cardiac applications, especially with the ability of PET to perform dynamic imaging to measure myocardial perfusion?myocardial blood flow (MBF) and coronary flow reserve (CFR), integrity of neural transmitters of the autonomic nervous system, and connecting cardiac efficiency with metabolism of myocardial substrates.
