PET/MR is a hybrid imaging modality that enables simultaneous acquisition of PET and MR images, and fuses functional or metabolic information obtained using PET and superior soft tissue contrast acquired using MR. Although PET has mostly been used for oncologic indications, PET/MR has significant potential for evaluating cardiac diseases. 18F-fluorodeoxyglucose PET/MR can evaluate not only inflammation and myocardial glucose metabolism, but also cardiac function, tissue edema, and myocardial fibrosis, simultaneously. Furthermore, using specific PET tracers, PET/MR enables the evaluation of various cardiac diseases. Although there are several technical issues that remain to be solved, PET/MR is a key modality for evaluating the pathophysiology of cardiac diseases.
