Inflammatory bowel disease imaging: Current practice and future directions

Figure 5 Perianal fistulizing Crohn’s disease depicted on magnetic resonance fistulography. Axial short tau inversion recovery (A) and coronal (B) T2-weighted (B) images demonstrate a complex perianal fistula at the 6 o’clock position (A; arrow) with an intersphincteric component (A; asterisks) as well as a transphincteric track extending to the skin to the right of midline (B; arrow).
