The purpose of the study was to evaluate the efficacy of a multi-contrast whole-body MRI protocol for tumor staging. The MRI protocol used a three-dimensional diffusion-weighted Echo-Planar, STIR, and T1 weighted Fast Spoiled Gradient Echo with fat suppression following gadolinium administration. Results of 15 patients with various primary malignancies were compared with whole-body PET/CT. The use of a high b value diffusion-weighted sequence in the Whole-Body MRI protocol improved the detection of secondary lesions, particularly lymph nodes.
