What is the role of FDG PET MRI in the nononcological setting?
FDG PET/MRI is most promising for the evaluation of patients with nononcological disorders that involve anatomic sites that are suboptimally evaluated at CT. In particular, PET/MRI may be particularly useful for evaluation of patients with neurologic, cardiovascular, and musculoskeletal nonneoplastic disorders. Available functional techniques afforded by MRI can further enhance detection and characterization of lesions. PET/MRI reduces radiation exposure compared to PET/CT, which is highly desirable, especially for pediatric patients and for those who undergo multiple examinations.
