目的：分析多层螺旋CT（MSCT）在肠缺血评价中的临床意义。方法收集惠州仲恺高新区人民医院急性腹痛临床怀疑肠缺血者40例，将其分为观察组20例，对照组20例，对两组患者进行检查，进行平扫、动脉期以及门脉期的检查，运用体积呈现技术、多平面建设技术和薄层最大密度的投影技术使动脉和门脉成像，对缺血肠管产生的病变进行有效的评价，把MSCT和数字减影血管造影的成像结果进行对比分析。结果当肠黏膜产生静脉血栓时，肠壁的厚度会增加，肠黏膜会产生水肿的现象，膜水的含量增加。当肠黏膜动脉出现血栓时，肠管道会出现张大的现象，肠腔内会集聚大量的气体。肠黏膜全层坏死的特征是肠壁内大量气体的聚集，其他的特征都可见于不同的病理和不同程度的肠缺血现象。结论多层螺旋CT（MSCT）对肠缺血能够进行准确的评价，有利于对肠缺血程度进行有效的判断，效果显著，值得临床推广。

Objective To analyze the clinical significance of multislice CT ( MSCT) in intestinal ischemia.Methods Collecting 40 patients with abdominal pain under the suspicion of intestinal ischemia , with 20 patients in the observation group and 20 in the control group.Doing plain scan , check during arterial phase and portal vein phase on patients of the two groups.Using volume phage display tech-nique, multiple plane construction technique and shadow casting technique of lamina maximum density to make artery and portal vein im -age, doing effective evaluation on the lesion of ischemia intestinal canal , and doing comparative analysis of MSCT and digital DSA image re-sults.Results When the intestinal mucosa has vein thrombosis , intestinal wall thickness increases , intestinal mucosa will produce the phe-nomenon of edema ,and membrane water content increases.When the intestinal mucosa has arterial thrombosis , the phenomenon of large bowel appears , a lot of gas gathers in the lumen.Intestinal mucosal full -thickness necrosis is characterized by extensive gas in the intesti-nal wall, and other features are visible in the different pathologies and with varying degrees of intestinal ischemia .Conclusion Multislice CT ( MSCT) in intestinal ischemia can evaluate accurately , and do favor to the effective judgment of the degree of intestinal ischemia.The effect is obvious ,and is worth clinical promotion.
