In lymphomas, whole-body MRI (WB-MRI), integrating structural / functional MRI sequences, offers an alternative radiation-free imaging method to standard radiological techniques. In this work, we evaluated multiple MRI sequences as part of a WB-MRI protocol for staging of 22 newly-diagnosed Hodgkin’s lymphoma and diffuse large B-cell lymphoma patients compared to reference-standard 18F-FDG PET-CT. We found that the performance of WB-MRI for nodal / extra-nodal disease detection and Ann-Arbor staging were at best when the entire protocol was reviewed. We observed an inferior diagnostic performance of WB-MRI using diffusion-weighted-imaging and an improved diagnostic performance when T2-weighted / post-contrast WB-MRI were reviewed.
