目的：探讨64排MSCT对急腹症缺血性肠病的应用价值。方法：对59例急腹症缺血性肠病患者进行64排MSCT检查，采用MPR、MIP、VR、CPR方式处理，对其影像学特征进行分析。结果：肠道壁厚增加，肠壁平扫密度和增强异常，肠管气体液体扩张，肠系膜血管直径和密度异常，肠系膜血管充盈缺损是急腹症缺血性肠病的CT表现，肠系膜血管内的充盈缺损影可作为确诊的直接依据，坏死段肠管与正常肠管在CT增强扫描时明显的强化程度的分界，可作为病变范围切除的手术依据。结论：64排MSCT对病变诊断准确，可以准确判断手术切除范围，可以作为临床对急腹症缺血性肠病诊断的首选方法，有较高的诊断价值。

Objective: To explore the value of 64-slice MSCT in the diagnosis of acute ischemic bowel disease. Method: Fifty-nine cases of acute abdomen of ischemic bowel disease were scanned with 64-slice MSCT and raw data were processed by MPR, MIP, VR and CPR. The imaging features were analyzed. Results: CT features of acute ischemic bowel disease included intestinal wall thickening, abnormal density and enhancement of intestinal wall, dilatation of intestine with gas and liquid, anomalies of mesenteric vascular diameter and density, filling-defect of mesenteric vessel. The filling-defect of mesenteric vessel could be the direct sign for diagnosis. There was obvious difference of enhancement degree between ischemic and normal intestine, which could be the basis for decision of resection range. Conclusion: 64-slice MSCT can serve as the primary method for the accurate diagnosis of ischemic bowel disease and can help to decide the resection range.
