Whole body imaging is a vital prerequisite for the management of patients with malignancies. Although bone scans and PETscans are routinely used in the follow up of oncology patients to evaluate metastases, their limited availability and inherent radiation exposure indicate that there is a strong need for a non invasive, radiation free, whole body imaging modality. Diffusion weighted, whole body magnetic resonance imaging with a background body signal suppression (DWIBS) MRI technique fulfills this much awaited need, as shown by the few examples which have been discussed in this article. DWIBS satisfactorily shows the presence and the extent of the bone as well as the soft tissue metastases. Other MRI sequences may be used when an in depth evaluation of the pathology is desired.
