目的 研究多层螺旋ＣＴ扫描及 其重建技术在诊断肠梗阻中的应用。方 法 选取徐州市第一人民医院2013年5月至 2015年11月74例疑似肠梗阻患者为研究对 象，采用16层螺旋CT扫描及图像重建，将 其诊断结果与手术病理进行分析对照。 结果 多层螺旋CT诊断肠梗阻存在的准确 率为94.6%，肠梗阻部位诊断准确率为 92.6%，肠梗阻病因诊断准确率为91.2%。 结论 多层螺旋CT及其重建技术可以清晰 显示肠梗阻病变，提高对肠梗阻病因的诊 断能力，值得临床应用和推广。

Objective To study application of multi-slice spiral CT scanning and reconstruction technique in the diagnosis of intestinal obstruction. Methods 74 patients suspected as intestinal obstruction in our hospital from May 2013 to November 2015 were selected as the research objects, 16 slice spiral CT scanning and image reconstruction were used, diagnostic results and surgical pathology were comparative analyzed. Results Diagnostic accuracy of multi-slice spiral CT in the diagnosis of intestinal obstruction was 94.6%, diagnostic accuracy in site of intestinal obstruction was 92.6%, diagnostic accuracy in causes of intestinal obstruction was 91.2%. Conclusion Multi-slice spiral CT and its reconstruction technique can show the lesions of intestinal obstruction clearly, improve diagnostic ability of causes of intestinal obstruction, it is worthy of clinical application and promotion.
