摘要
目的 :探讨多排螺旋CT(MDCT)在肠梗阻诊断中的价值。方法 :回顾性总结 2 8例临床怀疑为肠梗阻病例的MDCT检查结果 ,并将其中MDCT确诊为肠梗阻的病例与临床手术结果对照。扫描采用MDCT平扫或平扫后增强扫描 ,成像方法为薄层横断面、多方位重建成像。结果 :有 2 3例CT诊断为不同程度肠梗阻 ,其中 18例经手术治疗 ,CT报告梗阻部位正确的为 17例 ,病因诊断正确的为 17例 ,与手术结果对照 ,符合率均为 94 %。临床怀疑肠梗阻而MDCT检查后排除的另 5例中有 3例发现其他病变 ,MDCT检查结果与手术完全符合。结论 :MDCT对肠梗阻及其病因的诊断、血供情况的了解均有重大意义 。
Objective: To evaluate the value of multidetecter computed tomography(MDCT) in the diagnosis of bowel obstruction. Methods: Twenty-eight cases suspected of bowel obstruction underwent MDCT with or without intravenous contrast material. The thin slice axial image and MPR image were also analysed. Results: To the cases of bowel obstruction, MDCT could find out the obstructive part and show the blood supply, and comparing with the results of surgery, the accurate of the diagnosis of pathogeny was high (94%). To those negative cases, MDCT could also discover some pathology changes which might cause the clinical signs. Conclusion: As MDCT can find out the place and pathogeny of bowel obstruction, it is suggested the first choice in diagnosis of bowel obstruction.
