Computed tomography (CT) has become the imaging modality of choice for the investigation of patients with clinico-radiological suspicion of obstruction. Appropriate CT technique is discussed, with recommendations on how to improve diagnostic confidence and to reduce radiation dose. The performance of CT in the investigation of LBO is compared to that of the plain abdominal radiograph and contrast enema. CT is unrivalled in its ability to detect and characterise the cause of large bowel obstruction (LBO), identify complications, and guide appropriate treatment.
计算机断层扫描（CT）已成为对临床放射学怀疑有梗阻的患者进行检查的首选成像方式。本文讨论了适当的CT技术，并就如何提高诊断置信度和降低辐射剂量提出了建议。将CT在低位肠梗阻（LBO）检查中的表现与腹部平片和钡剂灌肠造影进行了比较。CT在检测和确定大肠梗阻（LBO）的病因、识别并发症以及指导适当治疗方面的能力无与伦比。
