Dual-Energy CT in the Detection of Bone Marrow Edema in the Sacroiliac Joints: Is There a Case for Axial Spondyloarthritis?
Radiology. 2019 Jan;290(1):165-166. doi: 10.1148/radiol.2018182224. Epub 2018 Oct 23.
Diagnosis and management of axial spondyloarthritis largely depends on identification of inflammatory activity and structural changes of the axial skeleton, with the sacroiliac joints being affected most often. Structural changes can usually be detected with plain radiography as a first-line imaging modality. However, because of inherent limitations such as the superposition of abdominal viscera, limited sensitivity and specificity must be expected (1).
