Purpose Of Review:
The purpose of this study was to provide an overview of the clinical applications of PET-MR in the setting of cardiac imaging with emphasis on specific scenarios where both techniques together provided added information.
Recent Findings:
Synergy of cardiac PET and MR fusion may hold similar promise eliminating ionizing radiation and improving tissue contrast. Future development of new hybrid scanners, use of new imaging tracers, and clinical applications are significant factors which will influence its use. Both positron emission tomography (PET) and cardiac magnetic resonance imaging (CMR) provide important anatomic and physiologic information with regard to the heart. Being able to combine the data from these two examinations in a hybrid technique allows for a more complete evaluation of cardiac pathology. While hybrid PET-CT has already established the utility of a combined imaging approach, the use of CMR in lieu of CT allows for elimination of ionizing radiation and for improved tissue contrast.
