Diffusion-weighted whole-body imaging with background body signal suppression (DWIBS): features and potential applications in oncology

Diffusion-weighted magnetic resonance imaging (DWI) provides functional information and can be used for the detection and characterization of pathologic processes, including malignant tumors. The recently introduced concept of “diffusion-weighted whole-body imaging with background body signal suppression” (DWIBS) now allows acquisition of volumetric diffusionweighted images of the entire body. This new concept has unique features different from conventional DWI and may play an important role in wholebody oncological imaging. This review describes and illustrates the basics of DWI, the features of DWIBS, and its potential applications in oncology.
