PET/MR Imaging:: Current Updates on Pediatric Applications.

PET/MR imaging is an integrated imaging system that combines the high soft tissue resolution of MR imaging with the quantitative data obtained from PET into a single system. It is a relatively new imaging technique but with potential clinical use in pediatric oncologic and nononcologic processes in additional to its role in research. It is particularly relevant in pediatric patients due to reduced radiation burden compared with PET/CT and the ability to obtain exquisite functional and anatomic imaging in a single imaging session, thereby reducing the number of anesthesia/sedations. This review article focuses on the current as well as future applications of PET/MR imaging in pediatric imaging, including both oncologic and nononcologic indications.
