Endoluminal magnetic resonance imaging (MRI) has become an important technique in the diagnostic work‐up of patients with anorectal diseases. The high spatial resolution of endoluminal MRI gives a detailed demonstration of the anal and rectal anatomy and pathology. This technique has been demonstrated to be superior to endoluminal sonography and body coil MRI. Endoanal MRI and phased‐array coil MRI seem to have comparable results in perianal fistulas, but comparative data are lacking. Phased‐array coil MRI is the imaging technique of choice for imaging rectal tumors, while endoluminal MRI is the alternative technique for imaging rectal tumors and the preferred technique for imaging anal tumors. Endoluminal MRI is superior to phased‐array coil MRI in fecal incontinence, as phased‐array coil MRI does not give the detailed spatial resolution required for evaluation of anal sphincter lesions.J.
