ABSTRACT


The objective of this article is to review the mechanisms, advantages and disadvantages of dual energy computed tomography (DECT) over conventional tomography (CT) in musculoskeletal imaging as DECT provides additional information about tissue composition and artifact reduction. This provides clinical utility in detection of urate crystals, bone marrow edema, reduction of beam hardening metallic artifact, and ligament and tendon analysis.
Keywords: Bone Marrow Edema, Dual Energy Computed Tomography, Metallic Artifact, Musculoskeletal Imaging, Urate Crystals
