DOMINGUEZ, A; PITRELLA, A  e  NOCETI, M. Perianal fistulas: magnetic resonance classification. Rev. argent. radiol. [online]. 2017, vol.81, n.2, pp.129-134. ISSN 1852-9992.  http://dx.doi.org/10.1016Zj.rard.2016.10.008.

Perianal fistulas are a prevalent problem in current medical practice, with a high impact on morbidity. The treatment is not exempt from complications, such as local recurrence and faecal incontinence. Magnetic resonance imaging (MRI) performs an essential role insurgical planning of these patients, since the high spatial resolution of the latest equipment provides more precise information of the pelvis anatomy, indicating the number and relationship of the fistulous tracks with the anal sphincter. The aim of this work is to identify the different types of fistulas based on MRI classification, with particular emphasis on the local anatomy and study techniques.
