Abstract

MR imaging is more accurate than digital rectal examination before surgery in detecting complex features of perianal fistulas. MR imaging is noninvasive, is highly accurate, and has low interobserver variability. With MR imaging, observers may better predict outcome than with initial surgical exploration. MR assessment that includes dynamic contrast-enhanced MR imaging and axial T2-weighted sequences (examination time, 20 min) provides the anatomic and pathologic information required to guide surgical management.
