目的探讨多层螺旋CT(MSCT)诊 断和鉴别小肠疾病的价值。方法 回顾性 分析我院2010年2月-2014年2月收治的 150例怀疑小肠疾病患者的临床资料，多 层螺旋CT和胃肠道造影检查资料完整， 以最终临床诊断结果作为对照，比较多 层螺旋CT及胃肠道造影检查的准确性、 灵敏度、特异度。结果 150例怀疑小肠 疾病患者经外科手术、内镜检查及活检 病理检查综合诊断后，最终确诊为小肠 疾病者90例(60%)，多层螺旋CT对小肠 疾病诊断的准确率为87.3%(131/150)， 灵敏度为78.9%(71/90)，特异度为 100.0%(60/60)，显著高于胃肠道造 影的准确率64.0%(96/150)，灵敏度 53.3%(48/90)，特异度80.0%(48/60)，差 异均具有统计学意义(均P＜0.05)。结论 多层螺旋CT对小肠肿瘤性疾病、肠梗阻及 炎症性疾病诊断中具有特征性表现，诊断 准确率、灵敏度及特异度均较高，对明确 和鉴别小肠疾病具有重要价值。

Objective to evaluate multislice CT (MSCT) in diagnosis and identify the value of the small intestinal diseases. Methods a retrospective analysis of our hospital in February 2010-February 2014 scores of the clinical data of 150 patients with suspected small bowel diseases, MDCT and gastrointestinal angiography examination data integrity, to the final clinical diagnosis by contrast, compare multislice computed tomography (CT) and angiography examination of gastrointestinal tract of accuracy, sensitivity, specific degrees. Results of 150 patients with suspected small bowel disease after surgery, endoscopic examination and biopsy pathological examination after comprehensive diagnosis and final diagnosis of small intestinal diseases of 90 cases (60%), MDCT of small intestine disease diagnostic accuracy was 87.3% (131/150), the sensitivity was 78.9% (71/90), 100.0% (60/60), significantly higher than that of the gastrointestinal angiography accuracy rate 64.0% (96/150), the sensitivity of 53.3% (48/90), a specific degree is 80.0% (48/60), differences were statistically significant (P < 0.05). Conclusion MDCT of small intestinal tumor disease, intestinal obstruction, and inflammatory disease diagnosis has the characteristic, diagnostic accuracy, sensitivity and speciality degree were higher, the clear and identify small intestine disease is of important value.
