MRI与多层螺旋CT在结肠癌致肠梗阻诊断中的价值分析

An Analysis on the Value of MRI and Multi-slice Spiral CT for Diagnosing Intestinal Obstruction Induced by Colonic Cancer

为分析MRI与多层螺旋CT在结肠癌致肠梗阻诊断中的价值,将200例结肠癌致肠梗阻患者随机分为观察组和对照组,每组100例。观察组采用MRI诊断,对照组采用多层螺旋CT诊断,比较2组诊断符合率、误诊率以及漏诊率。结果显示,观察组患者诊断符合率为95.00%,高于对照组的80.00%,2组比较差异有统计学意义(P <0.05)。观察组患者误诊率为3.00%、漏诊率为2.00%,对照组患者误诊率和漏诊率均为10.00%,观察组明显低于对照组(P <0.05)。结果表明,MRI与多层螺旋CT诊断结肠癌致肠梗阻临床效果相比较,前者更具有优势,且诊断符合率高,误诊率以及漏诊率较低,值得研究。

This study was to investigate the value of MRI and multi-slice spiral CT for diagnosing intestinal obstruction(IO)induced by colonic cancer,200 cases of this IO were randomly divided into observation group(100 cases,received MRI inspection)and control one(100 cases,multi-slice spiral CT);then compared coincidence diagnosis rate,misdiagnosis rate and missed diagnosis rate between the two groups.As results,in coincidence rate,in misdiagnosis rate and missed diagnosis rate,observation group was significantly and respectively high,lower and lower than control group[95.00%vs 80.00%,P<0.05;3.00%vs10%,P<0.05;and 2.00%vs 10.00%,P<0.05].Results show that MRI for diagnosing IO induced by colonic cancer has more advantages than multi-slice spiral CT such as higher coincidence rae,lower misdiagnosis rate and missed diagnosis rate,which is worth studying.
