目的评价螺旋CT及重建技术对肿瘤性肠梗阻的诊断价值。方法对25例经手术证实肿瘤性肠梗阻的CT表现及MPR、STS-MIP重建进行分析,并与手术病理进行对照研究。结果CT对肿瘤性肠梗阻的定位诊断和定性诊断正确率分别为100%及95%,MPR、STS-MIP可以分析供血动脉及引流静脉。结论螺旋CT及MPR、STS-MIP重建对肿瘤性肠梗阻的定性、定位诊断具有重要的临床价值。
Objective To evaluate the value of spiral CT and reconstruction in the diagnosis of intestinal obstruction. Methods Twenty - five cases of tumorous intestinal obstruction confirmed by CT and MPR and STS - MIP reconstruction were analyzed and compared with the surgical pathology. Results The accuracy of localization and qualitative diagnosis of tumor ileus by CT was 100% and 95% respectively. MPR and STS-MIP could analyze the feeding artery and drainage vein. Conclusion Spiral CT, MPR and STS-MIP reconstruction have important clinical value in the diagnosis and diagnosis of intestinal obstruction.
