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.
Conclusion:
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.

Radionuclide Testing
Radionuclide testing is a sophisticated medical technique for assessing gastrointestinal motility. It focuses on gastric emptying and colonic transit time. Radioactive markers track the movement of food through the digestive system, providing insights into gastrointestinal disorders.
