Abdominal and pelvic 18F-FDG PET/MR: a review of current and emerging oncologic applications

Abdom Radiol (NY). 2021 Mar;46(3):1236-1248. doi: 10.1007/s00261-020-02766-2. Epub 2020 Sep 19.

Abstract

Positron emission tomography (PET) using fluorodeoxyglucose (18F-FDG) combined with magnetic resonance imaging (MR) is an emerging hybrid modality that has shown utility in evaluating abdominal and pelvic disease entities. Together, the high soft tissue contrast and metabolic/functional imaging capabilities make this modality ideal for oncologic imaging in many organ systems. Its clinical utility continues to evolve and future research will help solidify its role in oncologic imaging. In this manuscript, we aim to (1) provide an overview of the various PET/MR systems, describing the strengths and weaknesses of each system, and (2) review the oncologic applications for 18F-FDG PET/MR in the abdomen and pelvis.

Keywords: Cancer; Oncology; PET/MR; PET/MRI; Staging.
