“Superscan” in diffusion-weighted imaging with background body suppression magnetic resonance imaging

(A) Diffusion-weighted images with background body suppression (DWIBS; inverted black-and-white greyscale) in a 78-year-old woman with primary bone marrow B-cell lympoma, showing high signal intensities (in black) in the mandible, vertebral body, clavicle, sternum, humeral head, pelvis, femur, and ribs. (B) 18-Fluorodeoxyglucose positron emission tomography–computed tomography showing radionuclide uptake in the patient’s mandible, vertebral body, clavicle, sternum, humerus, part of the ribs, pelvis and femur. Hepatosplenomegaly can also be observed and decreased radionuclide uptake in the kidneys and bladder (white arrow-heads). The artificial arc on the lower body is an indwelling urinary catheter.
