盆腔子宫内膜异位症CT、MRI诊断价值分析

Diagnostic Value of CT and MRI in Pelvic Endometriosis

目的探究对盆腔子宫内膜异位症患者实施CT、MRI诊断的效果。方法随机抽取2017年9月-2018年12月我院120例疑似盆腔子宫内膜异位症患者作为研究对象,对其均实施CT、MRI诊断,以手术病理检查结果为参照,对比CT、MRI的诊断效果。结果(1)经CT诊断显示,120例疑似患者中,93例被诊断为盆腔子宫内膜异位症,误诊9例,漏诊11例,经一致性检测可知,Kappa值为0.694。经MRI检查显示,120例疑似患者中,95例被诊断为盆腔子宫内膜异位症,误诊1例,漏诊1例,经一致性检测可知,Kappa值为0.889。(2)CT诊断盆腔子宫内膜异位症的敏感度、特异度、总准确率分别为88.42%、64.00%、83.33%;MRI诊断盆腔子宫内膜异位症的敏感度、特异度、总准确率分别为98.95%、96.00%、98.33%;统计发现,MRI的敏感度、特异度、总准确率较CT明显更高,P<0.05。结论对盆腔子宫内膜异位症患者实施MRI诊断的效果较CT更优,准确率更高。

Objective To investigate the effect of CT and MRI in the diagnosis of patients with pelvic endometriosis. Methods 120 patients with suspected pelvic endometriosis in our hospital from September 2017 to December 2018 were randomly selected as the study subjects. All of them were diagnosed by CT and MRI. The diagnostic effects of CT and MRI were compared with the results of surgical pathology. Results (1) CT diagnosis showed that 93 of 120 cases of suspected patients were diagnosed as pelvic endometriosis, 9 cases were misdiagnosed and 11 cases were missed. The Kappa value was 0.694 by consistency test. The results of MRI showed that among 120 suspected patients, 95 cases were diagnosed as pelvic endometriosis, 1 case was misdiagnosed and 1 case was missed. The Kappa value was 0.889 by consistency test.(2) The sensitivity, specificity and total accuracy of CT diagnosis of pelvic endometriosis were 88.42%,64.00% and 83.33% respectively. The sensitivity, specificity and total accuracy of MRI in the diagnosis of pelvic endometriosis were 98.95%,96.00% and 98.33% respectively. Statistics showed that the sensitivity,specificity and total accuracy of MRI were significantly higher than those of CT(P<0.05). Conclusion The effect of MRI diagnosis in patients with pelvic endometriosis is better than CT and the accuracy is higher.
