Recently High resolution diffusion-weighted imaging with background body signal suppression (DWIBS) and 3D images offers significant improvement for whole body screening strategies for detecting malignancy. The authors present a report of performing DWIBS in 10 patients with different kinds of tumors and bone metastasis in order to assess its ability in detecting bone metastasis. DWIBS data were compared with 11C- methionine positron emission tomography (MET-PET) and whole body bone scan. We believe DWIBS is a very sensitive method for detecting bone metastasis especially in pelvic cavity which is superior to MET-PET and bone scan; although for providing specifity side-by-side comparison with conventional MRI is necessary.
