摘　　要：目的:回顾分析64层CT冠状位重组图像对肠梗阻的辅助诊断价值。方法:回顾性分析100例(男40岁,女60岁,平均年龄51岁)可疑肠梗阻患者,每位患者均行增强扫描。2位医生独立对CT定位像,CT横断位,以及横断位结合冠状位图像进行分析。诊断可信度分为1～5级。结果:25例除外肠梗阻,75例患者经手术治疗。2位医生利用CT定位像、横断位、横断位结合冠状位图像诊断肠梗阻的平均敏感性和特异性分别是88%和83%,90%和86%,91.5%和87%。CT横断位结合冠状位图像诊断可信度高于横断位。结论:64层CT横断位结合冠状位图像可清晰显示梗阻部位。冠状位图像可增加诊断可信度,对诊断肠梗阻有较高价值。Objective：The added value of coronal reformation from isotropic voxels obtained with 64 MSCT were assessed retrospectively in diagnosis of intestinal obstruction.Methods：To retrospectively analysis one hundred consecutive patients（40 men and 60 woman,mean age 51 years） suspected with intestinal obstruction.All patients were performed with plain and enhancement scanning.Two independent readers blinded to the diagnosis interpreted the CT scans,transverse and then transverse plus coronal reformation imagings.confidence scored with 1～5 scale.Results：25 cases were normal.75 patients were conformed by surgical.Mean sensitivity and specificity of CT,transverse,and transverse plus coronal reformation imagings for the diagnosis of intestinal obstruction by two readers were 88% and 83%,90% and 86%,91.5% and 87%,respectively.In patients with intestinal obstruction,transverse plus coronal reformation imagings enhanced confidence in the diagnosis of intestinal obstruction.Conclusion：64 MSCT transverse plus coronal reformation imagings can easily determined the obstruction location.the coronal reformation imagings obtained from isotropic data added confidence of the diagnosis value.
