Enhanced computed tomography (CT) is frequently performed for possible bowel ischaemia. It has the distinct advantage of possible detection of the causes of ischaemia. Radiologists therefore need to be familiar with the spectrum of diagnostic CT signs. We present the CT imaging findings in surgically proven cases of small bowel ischaemia. In addition to signs pertaining to the underlying aetiological pathology, bowel dilatation, bowel wall thickening, mural gas, occlusion of mesenteric vessels, ascites and infarct of other abdominal organs were observed.
增强计算机断层扫描（CT）常用于排查可能的肠缺血情况。它具有能够检测缺血原因的显著优势。因此，放射科医生需要熟悉CT诊断征象的范围。我们展示了经手术证实的小肠缺血病例的CT影像学表现。除了与潜在病因病理学相关的征象外，还观察到肠扩张、肠壁增厚、肠壁积气、肠系膜血管闭塞、腹水以及其他腹部器官梗死。
