目的 探讨16层螺旋CT后处理技术对粘连性肠梗阻的诊断价值。方法 分析48例经手术、病理证实的粘连性肠梗阻术 前行16层螺旋CT扫描及MPR后处理的影像表现，与临床手术和病理结果进行对照研究。结果 48例中，CT横断面图 像、MPR图像均显示了肠梗阻的存在；单独根据横断面图像能确定38例(81.2％)的梗阻部位，而结合MPR图像可以确 定45例(93.8％)的梗阻部位；有7例(87.5％)肠壁缺血或绞窄病例均为两种方法所显示。结论 16层螺旋CT及后处理 技术是术前无创性诊断粘连性肠梗阻的重要方法，在显示粘连性肠梗阻的存在，确定梗阻部位和肠道血运状态方面 具有重要的临床价值。

Objective To evaluate the diagnostic value of 16-slice spiral CT and its post-processing techniques in adhesive intestinal obstruction. Methods Clinical data of 48 cases of adhesive intestinal obstruction revealed by plane and contrast-enhanced 16-slice spiral CT manifestations and MPR post-processing techniques were analyzed and compared with the results of surgical findings and pathology. Results Among the 48 cases Both axial and MPR images correctly depicted the presence of intestinal obstruction. Based on CT axial view,the site of intestinal obstruction were determined in 38(81.2%), while the combination with MPR images improved the diagnostic performance to 45(93.8%). Both axial and MPR images correctly revealed the presence of intestinal ischemia or strangula-tion in 7 (87.5%)patients. Conclusion 16-slice spiral CT and its post-processing techniques have an important clinical value in evaluating the site and the circulation status of adhesive intestinal obstruction.
