Magnetic resonance imaging in perianal fistulas-A pictorial atlas

Gururaj Sharma et al. Indian J Gastroenterol. 2016 Sep.

Abstract

This pictorial atlas provides a review of perianal fistulas with a brief description of the relevant anatomy, technique of imaging, and examples of various fistula types. Magnetic resonance imaging is highly accurate for depiction of both the primary tract and its secondary branches as well as abscesses. It is useful in the accurate preoperative classification of perianal fistulas and allows institution of the correct surgical procedure, thereby reducing the chances of recurrence or complications from occurring.

Keywords: Intersphincteric; MRI; Perianal fistula; Supralevator; Transsphincteric.
