Abstract.

Diffusion-weighted imaging (DWI) is one of magnetic resonance imaging (MRI) sequences providing qualitative as well quantitative information at the cellular level. It has been widely used for various applications in the central nervous system. The purpose of this article is to describe the clinically relevant basic concepts of DWI, techniques to perform abdominal DWI, its analysis and applications in extracranial MR imaging, in addition to a brief overview of whole body DWI MRI. Over the past decade, various extracranial applications of DWI have been increasingly explored, as it may detect changes even before signal alterations or morphological abnormalities become apparent on other pulse sequences. Initial results from abdominal MRI applications are promising, particularly in  oncological settings and for the detection of abscesses.

Key words: EXTRACRANIAL. DWI. MRI
