Dual-Energy Computed Tomography and Beyond: Musculoskeletal System

Emtenen Meer et al. Radiol Clin North Am. 2023 Nov.

Abstract

Traditional monoenergetic computed tomography (CT) scans in musculoskeletal imaging provide excellent detail of bones but are limited in the evaluation of soft tissues. Dual-energy CT (DECT) overcomes many of the traditional limitations of CT and offers anatomical details previously seen only on MR imaging. In addition, DECT has benefits in the evaluation and characterization of arthropathies, bone marrow edema, and collagen applications in the evaluation of tendons, ligaments, and vertebral discs. There is current ongoing research in the application of DECT in arthrography and bone mineral density calculation.

Keywords: Collagen analysis; Dual-energy CT; Gout; Musculoskeletal imaging.
