Orthopedic Applications of Single-photon Emission Computed Tomography/Computed Tomography in Identifying Pain Generators in the Pre- and Post-operative Patient

George O. Theobald, Robert W. Foley, Sean Scattergood, Stewart Redman et autres

Postoperative and benign bone pathologies can sometimes be difficult to elicit on purely anatomical-based imaging. Single-photon emission computed tomography-computed tomography (SPECT-CT) is an established modality with emerging applications in the musculoskeletal field that combines cross-sectional structural imaging with the metabolic data. It …
