Abstract:
OBJECTIVE. Dual-energy CT (DECT) involves the acquisition of CT attenuation data at two different energy levels. In musculoskeletal imaging, gout detection is the most validated clinical indication for DECT. However, there is emerging evidence for several other clinical musculoskeletal applications, including metal artifact reduction and bone marrow imaging for traumatic, neoplastic, and inflammatory processes. CONCLUSION. In this article, we review the current role of DECT in musculoskeletal imaging, primarily focusing on nongout entities.
