西门子128层AS螺旋CT小肠造影在小肠病变诊断中的应用

Application of Siemens 128-Slice AS Spiral CT Enterography in the Diagnosis of Intestinal Lesions

目的探讨西门子128层AS螺旋CT小肠造影诊断小肠病变的价值。方法76例高度疑似小肠病变患者均经128层螺旋CT小肠造影、手术病理或内镜检查,以手术病理或内镜检查结果作为“金标准”,分析CT小肠造影对小肠病变的诊断效能。结果76例高度疑似小肠病变患者经手术病理或内镜检查确诊68例,占89.47%。CT小肠造影诊断小肠病变的灵敏度、特异度、准确度分别为97.06%、87.50%、96.05%。CT小肠造影与手术病理或内镜诊断小肠病变类型具有极好一致性(Kappa=0.801)。结论西门子128层AS螺旋CT小肠造影诊断小肠病变具有较高的灵敏度、特异度及准确度,可有效鉴别小肠病变类型。

Objective To explore the value of Siemens 128-slice AS spiral CT enterography in the diagnosis of intestinal lesions.Methods 76 patients with highly suspected intestinal lesions underwent 128-slice spiral CT enterography and surgical pathology or endoscopy.The results of surgical pathology or endoscopy were taken as the"gold standard"to analyze the diagnostic efficacy of CT enterography for intestinal lesions.Results 68 cases(89.47%)of 76 patients with highly suspected intestinal lesions were confirmed by surgical pathology or endoscopy.The sensitivity,specificity and accuracy of CT enterography in the diagnosis of intestinal lesions were 97.06%,87.50%and 96.05%respectively.There was a very good agreement between CT enterography and surgical pathology or endoscopy in the diagnosis of intestinal lesions(Kappa=0.801).Conclusions Siemens 128-slice AS spiral CT enterography has high sensitivity,specificity and accuracy in the diagnosis of intestinal lesions,and can effectively identify the types of intestinal lesions.
