摘要
目的分析双源螺旋CT小肠动态增强扫描对炎症性肠病的诊断价值。方法60例疑似炎症性肠病患者均行双源螺旋CT小肠动态增强扫描检查,以病理诊断结果作为“金标准”,分析双源螺旋CT小肠动态增强扫描对克罗恩病及溃疡性结肠炎的诊断效能,比较两种炎症性肠病的影像学特征。结果病理检查结果显示,60例疑似炎症性肠病患者中52例确诊为炎症性肠病,包括克罗恩病36例,溃疡性结肠炎16例。双源螺旋CT小肠动态增强扫描诊断克罗恩病的灵敏度为94.44%(34/36),特异度为87.50%(21/24),准确度为91.67%(55/60);诊断溃疡性结肠炎的灵敏度为93.75%(15/16),特异度为95.45%(42/44),准确度为95.00%(57/60)。克罗恩病的肠腔狭窄及多节段性病变占比均高于溃疡性结肠炎(P<0.05)。结论双源螺旋CT小肠动态增强扫描对炎症性肠病的诊断价值较高,依据影像学特征可有效鉴别克罗恩病、溃疡性结肠炎。
Objective To analyze the diagnostic value of dual-source spiral CT dynamic enhanced scan of the small intestine for inflammatory bowel diseases.Methods Sixty patients with suspected inflammatory bowel diseases underwent dual-source spiral CT dynamic enhanced scan of the small intestine.The pathological diagnosis results were used as the"gold standard"to analyze the diagnostic efficacies of dual-source spiral CT dynamic enhanced scan of the small intestine for Crohn's disease and ulcerative colitis.The imaging features of the two inflammatory bowel diseases were compared.Results The results of pathological examination showed that 52 of 60 patients with suspected inflammatory bowel diseases were diagnosed as inflammatory bowel diseases,including 36 cases of Crohn's disease and 16 cases of ulcerative colitis.The sensitivity of dual-source spiral CT dynamic enhanced scan of the small intestine in the diagnosis of Crohn's disease was 94.44%(34/36),the specificity was 87.50%(21/24),and the accuracy was 91.67%(55/60);The sensitivity,specificity and accuracy in the diagnosis of ulcerative colitis were 93.75%(15/16),95.45%(42/44)and 95.00%(57/60),respectively.The proportions of intestinal stenosis and multi-segmental lesions in Crohn's disease were higher than those in ulcerative colitis(P<0.05).Conclusions Dual-source spiral CT dynamic enhanced scan of the small intestine has high diagnostic value for inflammatory bowel diseases.According to the imaging features,Crohn's disease and ulcerative colitis can be effectively identified.
