Abstract: In applying diffusion-weighted whole-body imaging with background body signal suppression (DWIBS) technique, DW-MR images are acquired during free breathing, which results in images with high signal-to-noise ratio using relatively thin image sections (4–5 mm). Image acquisition during free breathing is possible because bulk tissue motion, including respiratory motion, may be considered as types of coherent motion, which do not result in significant signal loss unlike intravoxel incoherent motion, which reflects random water motion at a cellular level. The concept of DWIBS allows handling of the acquired images as a volumetric dataset and it exploits both prolonged T2 relaxation time and impeded diffusion that the majority of solid lesions (both benign and malignant) exhibit as mechanisms for image contrast, which is used for clinical evaluation of diseases.

Diffusion-weighted MR imaging of the brain.
TL;DR: Because stroke is common and in the differential diagnosis of most acute neurologic events, diffusion-weighted MR imaging should be considered an essential sequence, and its use in most brain MR studies is recommended.
