Abstract:
Photon-counting computed tomography is the newest technological advancement in CT imaging allowing for an improved spatial resolution, inherent spectral information, and significant radiation dose reduction. These benefits may enhance diagnostic confidence and accuracy for radiologists and clinicians. Multiple clinical applications in musculoskeletal radiology benefit from this technology, including the reduction of metal artifacts, improved visualization of bone marrow edema, and better assessment of crystal arthropathies. This narrative review presents a comprehensive summary of the current advancements and applications of this emerging technology within musculoskeletal radiology using several illustrative cases.
