Abstract

The evaluation of the anal canal is often necessary for Crohn’s disease patients considering its frequent involvement.

The typical pathologic conditions are represented by fistulas and abscesses.

MRI of the anal region must be performed through an encoded protocol consisting of T2-weighted, T1-weighted before and after Gadolinium injection and diffusion-weighted scans.

Acquisition planes must be set according to the longitudinal and axial axis of the canal.

The latter parameters are of the utmost importance not only for the radiological assessment but also in case of surgical planning.

Nevertheless, several conditions of various nature, related or not to Crohn’s disease, can be assessed through this technique, from inflammation to malignancies.
