Hot Topics of Research in Musculoskeletal Imaging: PET/MR Imaging, MR Fingerprinting, Dual-energy CT Scan, Ultrashort Echo Time.

We aimed to review the latest cutting-edge trends in emerging techniques of musculoskeletal imaging. This study reviews the current status and the preliminary studies of Magnetic Resonance Fingerprinting (MRF), Ultrashort Echo Time (UTE) sequence, Positron Emission Tomography (PET)/MR and Dual-Energy CT scan (DECT) in various oncologic and non-oncologic conditions of the musculoskeletal system. The current application, current and future research trends and limitations of each imaging technique were discussed. There are substantial potentials in MRF, UTE, PET/MR and DECT for characterization of various musculoskeletal disorders. Further dedicated studies in various fields are necessary.
