title: [CT diagnosis of midgut malrotation].
abstract: OBJECTIVE
  To explore the diagnostic value of CT in midgut malrotation.
  
  
  METHODS
  The CT appearances of 16 patients with midgut malrotation were analyzed retrospectively.
  
  
  RESULTS
  The features of CT manifestation in 16 cases were as follows: (1) Horizontal part of duodenum could not reach medioventral line or could reach it but encircled right-down behind the superior mesenteric artery(SMA). (2) Ectopic ileocecal junction. (3) Jejunum located in right-middle abdomen while ileum in left abdomen. (4) A clockwise or counterclockwise rotation of the superior mesenteric vein (SMV) around the SMA. (5) Mid-gut volvulus.(6)Accompanied by other malformations.
  
  
  CONCLUSIONS
  Ambulation of duodenum, location of the small intestine and colon as well as anatomical position of mesenteric vessels should be intensively observed in order to exclude midgut malrotation.
