Abstract
OBJECTIVE: The purpose of this article is to review MRI technique, relevant anatomy, and MRI classification systems for the assessment of perianal fistulising disease. We present a stepwise approach to the assessment of perianal fistulas on MRI utilizing a systematic reporting format. CONCLUSION: MRI is invaluable for the assessment of perianal fistulas. A systematic report can help communicate the anatomy of complex fistulising disease to assist with optimal management.
