MRI demonstration of peritoneal ligaments and mesenteries.

The normal appearances of 14 peritoneal ligaments and mesenteries were demonstrated by magnetic resonance imaging (MRI). Antegrade or retrograde air introduction was employed to distend and mark the gastrointestinal tract. Delineation of these ligaments and mesenteries was helped by the presence of ascites and air-distended bowel loops. The different intraperitoneal compartments are also demonstrated.
