The purpose was to evaluate WB-MRI using DWI and continuous table movement (CTM) STIR sequences as a new modality for the workup of FUO without radiation exposure and less effort compared to scintigraphy. 6 patients with FUO were examined at 3 T using a combined protocol with coronal WB diffusion-weighted sequences (EPI-SpinEcho), coronal WB CTM STIR sequences and axial contrast-enhanced T1-weighted GRE (VIBE)-sequences as reference. In 5 patients pyogenic foci were detected. The first results using WB-DWI and CTM STIR-sequences are promising for the workup of FUO. The combined WB-DWI and CTM STIR protocol might replace leucocyte scintigraphy as diagnostic standard of reference in the future.
