MSCTE在小肠炎性病变的影像诊断价值研究

Research on image diagnosis of multislice spiral CT enterography in small bowel inflammatory diseases

目的评价MSCTE对小肠炎性病变影像诊断价值。方法本院疑诊为小肠炎性病变患者103例,A组2.5%等渗甘露醇41例,B组纯水组62例,分析各种小肠炎性病变的MSCTE表现,分别计算出两种不同检查方法的敏感度、特异度、阳性预测值及阴性预测值。结果 A组2.5%等渗甘露醇组敏感度、特异度、阳性预测值、阴性预测值,高于B组纯水组。两种方法比较其敏感度、阳性预测值差异有统计学意义(P<0.05)。结论 MSCTE能够有效评价小肠炎性病变,全方位展示肠道内、外病变,具有较高的病变检出率及诊断准确率,可为小肠炎性病变提供重要诊断依据。

Objective To evaluate the value of imaging diagnosis of multislice spiral CT enterography in small bowel inflammatory disease.Methods In the clinical data of 103 patients with symptoms of suspected small bowel inflammatory diseases,MSCTE features of various kinds of small bowel inflammatory diseases were analyzed by comparing with the results of 2.5%isotonic mannitol in 41 cases and the pure water in 62 cases.The sensitivity,specificity,positive predictive value and negative predictive value in 2.5%isotonic mannitol and pure water were calculated.Results The sensitivity,specificity,positive predictive value and negative predictive value in 2.5%isotonic mannitol were higher than pure water.Comparing the difference between the sensitivity and positive predictive value by two modalities has statistical significance(P<0.05).Conclusion MSCTE is a effective method for evaluating small bowel inflammatory disease,and enough clear to show small bowel and surrounding tissue,which has high detectable and diagnostic rates.So,the MSCTE can provide important basis for the diagnosis of the small bowel inflammatory disease.
