Abstract
Magnetic resonance imaging (MRI) has become an important imaging technique for otorhinolaryngology. The aim of the present CME contribution for ENT physicians is to provide an overview of the advantages and disadvantages as well as the possibilities of head and neck MRI and to summarize the main clinical applications of the various MRI sequences. Basic sequences (T1w, T2w, T1wC+) and fat suppression sequences (TIRM/STIR, Dixon, Spectral Fat sat) are the basis for evaluating inflammation, congenital lesions and tumors. High-resolution 3D sequences - SSFP (CISS, FIESTA), SPACE, VISTA, 3D-FLAIR - are used to assess the cranial nerves, labyrinth, and endolymphatic hydrops in Morbus Menière. Vascular sequences (3D-TOF, TWIST/TRICKS) are used in vascular contact syndromes and vascular malformations. Diffusion sequences (EPI-DWI, non-EPI-DWI, RESOLVE) are used for the evaluation of cholesteatoma, assessment of malignancy and evaluation of response to radio (chemo) therapy.
