Abstract
Objective To improve the ac cu racy rate of spiral CT diagnosing intestinal volvulus. Methods To analysis the CT findings of 9 cases of intestinal volvulus proved by o peration, the main reconstruction techniques were multiplanar reformation (MPR) and sliding thin-slab maximum intensity projection (STS-MIP). Re sults All the 9 cases were diagnosed accurately, the main signs were “whirlpool” of intestine (6 cases) and vessels(9 cases),“target loop”(2 ca ses)、“beak”(6 cases). Conclusion “Whirlpool” of vess els is a specific sign to diagnose intestinal volvulus, “target loop”, reduce d enhancement of intestinal wall and ascites are the reliable signs to strangula ted intestinal obstruction. Spiral CT and reconstructions have important value t o diagnose the intestinal volvulus.
