Use of dual-energy CT to detect and depict bone marrow oedema in rheumatoid arthritis: is it ready to substitute MRI?

MRI can visualise and depict bone marrow oedema, which is known to be a strong independent predictor for radiographic progression in patients with rheumatoid arthritis (RA).1 2 Recent advances in dual-energy CT have enabled the direct visualisation of traumatic bone marrow oedema with high sensitivity and specificity through implementation of virtual non-calcium (VNCa) images.3–7 We have recently read Jans and colleagues’ letter8 entitled,...
