Abstract：Objective:To discuss the imaging characteristics of sigmoid volvulus(SV)with multi-slice spiral computed tomography (MSCT) and improve the level of preoperative diagnosis in patients of SV.Methods:MSCT examinations were performed in 15 caseswith sigmoid volvulus proved by pathology or colonoscope reposition, and the CT imaging characteristics were analyzed and summarized retrospectively. Results:The MSCT signs of 15 cases of SV includedall 15 cases had sigmoid dilated,4 cases showed intestinal damage (bowel wall thickening,mesenteric edema,mesenterium effusion and ascites etc.). 14 cases with invertedU-shape were showed on scanogram scanning,13 cases of round belly sign, 11 cases ofbeak sign on cross-section scanning. MPR showed 10 cases of cross sign and 9 cases of whirl sign; Contrast-enhanced CT and CTA showed the enhancement of bowel wall weakened in 3 cases, 1 case ofsmall vessel occlusion of mesentery, 2 cases of mesenteric artery rotation.Conclusion:The MSCT features of SV had some characteristics,especiallyhad a great value in guideline for clinical therapy in the estimate of intestinal damage.
