Response to: ‘The use of dual-energy CT to detect and depict bone marrow oedema in rheumatoid arthritis: is it ready to substitute MRI?’ by Wu et al

We wish to thank the authors for their interest in our paper.1 We agree that the corresponding dual-energy CT (DECT) and MRIs in the published paper2 show a certain degree of visual discrepancy. However, when comparing the two imaging modalities on a single slice, discrepancies may occur due to differences in the imaging plane, slice thickness, postprocessing, as well as differences between both techniques to detect a certain feature. In our study, a global evaluation of all slices in all available planes was performed. It is recognised …
