第一部分MRI在子宫内膜癌术前诊断及分期中的价值目的探讨MRI在子宫内膜癌术前诊断及分期中的价值。材料和方法收集自2010年1月至2012年12月间上海瑞金医院妇科住院治疗的疑子宫内膜癌病例,手术前对所有病例行盆腔MRI检查,以术后病理结果为金标准,与MRI检查结果进行对照分析。应用SPSS13.0统计学软件,分析①MRI诊断子宫内膜癌不同分期的准确度、敏感度、特异度,②MRI诊断子宫内膜癌肌层浸润深度的准确度、敏感度、特异度,③MRI诊断子宫内膜癌宫颈受累情况的准确度、敏感度、特异度。结果经病理证实子宫内膜癌病例76例,年龄范围38~88岁。分析显示:①MRI诊断子宫内膜癌Ⅰa期、 Ⅰb期、 Ⅱ期、Ⅲ期及Ⅳ期的准确度分别为85.53%、84.21%、90.79%、90.79%、98.68%,MRI正确判断分期64例,诊断分期总的准确度为84.21%;②子宫内膜癌病例肌层浸润深度为浅肌层浸润42例,深肌层浸润34例。MRI对肿瘤浸润浅肌层的准确度、敏感度、特异度分别为85.53%、81.63%、92.59%,浸润深肌层的准确度、敏感度、特异度分别为85.53%、92.59%、81.63%;③MRI诊断子宫内膜癌病例宫颈受累情况的准确度、敏感度、特异度分别为88.16%、63.64%、92.31%。结论MRI对子宫内膜癌术前诊断及分期的准确度较高,诊断肌层浸润深度及宫颈受累情况,较病理结果具有一致性,对临床治疗方案的选择及预后具有重要临床意义。MRI对软组织分辨率高,且检查无创、无辐射,可作为子宫内膜癌术前诊断与分期的常规影像学检查方法。第二部分MRI在子宫颈癌术前诊断及分期中的价值目的探讨MRI在子宫颈癌术前诊断分期和盆腔淋巴结转移中的价值。材料和方法收集自2010年1月至2012年12月间上海瑞金医院妇科住院治疗的疑子宫颈癌病例,手术前对所有病例行盆腔MRI检查,以术后病理结果为金标准,与MRI检查结果进行对照分析。应用SPSS13.0统计学软件,分析①MRI诊断子宫颈癌病例不同分期的准确度、敏感度、特异度,②MRI诊断子宫颈癌病例宫旁受累情况的准确度、敏感度、特异度,③MRI对子宫颈癌病例盆腔淋巴结转移诊断的准确度、敏感度、特异度。结果经病理证实子宫颈癌病例88例,年龄范围27~73岁。分析显示:①MRI评估子宫颈癌病例Ⅰb期、Ⅱa、Ⅱb期、Ⅲa、Ⅲb期及Ⅳa、Ⅳb期的准确度分别为76.92%、60.26%、69.23%、100%、97.44%、97.44%、98.72%,MRI正确判断分期57例,分期总的诊断准确度为73.08%;②MRI诊断子宫颈癌病例宫旁受累的准确度、敏感度、特异度分别为71.59%、31.82%、84.85%;③MRI诊断子宫颈癌淋巴结转移的准确度、敏感度、特异度分别为82.95%、60%、87.67%。结论MRI对子宫颈癌术前诊断及分期的准确度较高,可较为准确显示宫旁受累及淋巴结转移情况,与病理诊断符合率高,对临床治疗方案的选择及预后具有重要价值。MRI对软组织分辨率高,且检查无创、无辐射,可作为子宫颈癌术前诊断与分期的常规影像学检查方法。Part OneTHE VALUE OF MRI IN THE PREOPERAYIVEDIAGNOSIS AND STAGING OF ENDOMETRIALCARCINOMAObjectiveTo explore the value of MRI in evaluation of the staging in the endometrialcarcinoma.Marerials and methodsSeventy six cases of endometrial cancer in Shanghai Ruijin Hospital fromJanuary2010to December2012were collected. All patients underwent pelvicMRI examination before operation. The result of MRI was compared withsurgical pathologic reports. The data was analyzed using SPSS13.0statisticalsoftware.①the accuracy, sensitivity and specificity of MRI in evaluation thestaging in the endometrial carcinoma were analyzed, respectively.②theaccuracy, sensitivity and specificity of MRI in evaluation the invasion in theendometrial carcinoma were analyzed, respectively. And③the accuracy,sensitivity and specificity of MRI in evaluation the cervical invasion in theendometrial carcinoma were analyzed, respectively.ResultsIn seventy six patients with endometrial carcinoma proved by surgicalpathology, the age of the patients range from38to88.①The accuracy of MRIin evaluation the endometrial carcinoma of staging Ⅰ A, Ⅰ B, Ⅱ, Ⅲ and Ⅳwas85.53%,84.21%,90.79%,90.79%,98.68%, respectively, the total accuracy was
