Abstract

Diffusion-weighted imaging (DWI) has become an integral part of MRI. Knowledge of the basic principles of DWI and its pitfalls are imperative in the proper application of this technique. We illustrate potential pitfalls of DWI in oncologic imaging.

Keywords: MRI; diffusion; oncologic imaging; pitfall; tumour.
