PET/MR imaging: current and future applications for cardiovascular disease.

PET and magnetic resonance (MR) imaging have each become essential tools in the workup and management of cardiac patients. Combined PET/MR systems have recently been developed, allowing for single-session imaging using both modalities. This new technology holds great promise for cardiac applications given the different, yet complementary, information each modality provides. Research in this area is still nascent, although early studies have been promising.
