[Diffusion-weighted MR imaging of the head and neck].
Diffusion weighted MR imaging is increasingly being used for the imaging of head and neck pathology. This imaging technique now replaces CT and conventional MR imaging for the initial diagnosis of cholesteatoma and detection of recurrent disease. Diffusion weighted imaging has also proven to be valuable for additional head and neck pathologies and currently has three main indications: detection and characterization of tumors, regional tumor staging, and prediction of tumor response to treatment and follow-up. In the recent months, several publications have discussed the use of diffusion weighted imaging for head and neck pathology and this technique has become virtually indispensable for the MR imaging evaluation of the head and neck.
