摘要
目的:探讨CT与MRI诊断结肠癌致肠梗阻的应用价值。方法:选择笔者所在医院2017年6月-2019年6月收治的50例结肠癌致肠梗阻患者,依次采用CT和MRI进行检查,对比两种方式检查的效果。结果:MRI检出率为100%,无漏诊,CT检出率为90.00%,漏诊率为10.00%,组间比较差异有统计学意义(P<0.05)。MRI对于肿块侵犯浆膜下、狭窄段、肠旁组织缺血性结肠炎检出率高于CT(P<0.05)。T1WI图像显示肿块呈等低信号,局部管腔狭窄;T2WI-SPAIR图像显示乙状结肠累及浆膜下;MRI增强图像显示乙状结肠明显不均匀强化。结论:CT与MRI在结肠癌致肠梗阻的诊断中,MRI的应用价值更高,MRI对于侵犯浆膜下、狭窄段、肠旁组织缺血性结肠炎等检出率高于CT,诊断准确率高,漏诊率低,值得临床推广使用。
Objective:To explore the application value of CT and MRI in the diagnosis of intestinal obstruction caused by colon cancer.Method:Fifty patients with colon cancer-induced intestinal obstruction treated in our hospital from June 2017 to June 2019 were selected and examined by CT and MRI in order.And the effects of the two methods were compared.Result:The MRI detection rate was 100%,there was no missed diagnosis,the CT detection rate was 90.00%,and the missed diagnosis rate was 10.00%.There was a statistically significant difference between the groups (P<0.05).The detection rate of MRI for ischemic colitis of masses invading the subserosal,stenotic and para-intestinal tissues were higher than those of CT (P<0.05).On T1WI,the mass showed isolow signal and local lumen was narrow.On T2WI-spair,the sigmoid colon was involved in subserosal.On MRI,the sigmoid colon was significantly enhanced unevenly.Conclusion:CT and MRI are more valuable in the diagnosis of colon cancer-induced intestinal obstruction.MRI has a higher detection rate for invasion of subserosal,stenotic,and intestinal ischemic colitis than CT,and the diagnosis is accurate.The high rate and low rate of missed diagnosis are worthy of clinical promotion.
