Advanced Musculoskeletal Applications of Dual-Energy Computed Tomography.

Dual-energy CT (DECT) is a rapidly growing tool in musculoskeletal radiology. It has been validated as an accurate imaging modality for the assessment of gout and bone marrow edema. DECT can be used to reduce metal artifacts. A few studies have shown its ability to calculate bone mineral density and examine pathologic states in tendons and ligaments. Its capacity for material separation suggests its emergence as a technique for arthrography, and for the evaluation of intervertebral discs and other inflammatory arthropathies.
