The assessment of both the pattern and activity of myocardial injury has important implications for the clinical management of patients with cardiovascular disease. Comprehensive evaluation of these has previously been challenging using a single imaging modality.
Cardiac magnetic resonance (CMR) with late gadolinium enhancement (LGE) has become well established for differentiating the patterns of injury observed in a range of conditions. 18F-fluorodeoxyglucose positron emission tomography (FDG-PET) is widely used to measure inflammation activity in the vasculature and myocardium.
The advent of simultaneous PET/MR imaging now allows combination of these 2 techniques alongside cardiac function with major advantages in terms of image coregistration, interpretation, and radiation exposure. In this report, we present 3 clinical cases (Figures 1, 2, and 3, Online Videos 1, 2, 3, and 4) where the initial etiology and activity of the disease process was unclear but resolved after addition of FDG PET/MR (Biograph mMR, Siemens, Healthineers, Erlangen, Germany) to the clinical context. A fourth case (Figure 4, Online Videos 5 and 6) highlights the potential for false positive FDG signal in the myocardium (1).
Hybrid FDG-PET/MR offers complementary information with the ability to image myocardial function, the pattern of injury, and disease activity in a single scan.
