摘　　要：目的观察磁共振成像(MRI)检查在宫颈癌诊断及分期中价值。方法200例疑似宫颈癌患者,均进行1.5 T的MRI扫描,分析MRI检查结果及MRI对宫颈癌患者治疗前原发肿瘤-淋巴结-远处转移(TNM)分期诊断符合情况。结果200例疑似患者经病理结果证实宫颈癌190例,包括腺癌7例与鳞癌183例,余下的10例均为高级别宫颈上皮内瘤变。MRI检出176例,检出率是88.00%(176/200);灵敏度是91.58%(174/190),特异度是80.00%(8/10),准确率是91.00%(182/200)。200例疑似患者经病理结果证实宫颈癌190例,TNM分期中Ⅰa期50例,Ⅰb期35例,Ⅱa期29例,Ⅱb期40例,Ⅲa期27例,Ⅲb期9例,Ⅲc期、Ⅳa期、Ⅳb期均0例。MRI检出阳性176例,TNM分期中Ⅰa期49例,Ⅰb期33例,Ⅱa期29例,Ⅱb期37例,Ⅲa期20例,Ⅲb期8例,Ⅲc期、Ⅳa期、Ⅳb期均0例。MRI对治疗前宫颈癌患者TNM分期Ⅰa、Ⅰb、Ⅱa、Ⅱb、Ⅲa、Ⅲb、Ⅲc、Ⅳa、Ⅳb期的诊断符合率分别为96.00%(48/50)、94.29%(33/35)、93.10%(27/29)、87.50%(35/40)、74.07%(20/27)、88.89%(8/9)、0、0、0。结论对疑似宫颈癌的患者采取MRI扫描检查,灵敏度、准确度及特异度均较高;同时MRI检查对宫颈癌各分期诊断符合率都较高,MRI在宫颈癌诊断、治疗前分期中均有显著效果,值得推广。Objective To observe the value of magnetic resonance imaging(MRI)in diagnosis and pretreatment staging of cervical cancer.Methods All 200 patients with suspected cervical cancer underwent MRI scanning at 1.5 T.The results of MRI were analyzed,as well as the diagnostic compliance of MRI on tumor-nodemetastasis(TNM)staging of cervical cancer patients before treatment.Results Among the 200 suspected patients,190 cases of cervical cancer were confirmed by pathology,including 7 cases of adenocarcinoma and 183 cases of squamous cell carcinoma,and the remaining 10 cases were high-grade cervical intraepithelial neoplasia.MRI detected 176 cases,the detection rate was 88.00%(176/200);the sensitivity was 91.58%(174/190),the specificity was 80.00%(8/10)and the accuracy was 91.00%(182/200).Among the 200 suspected patients,190 cases of cervical cancer were confirmed by pathology,in which 50 cases were in stage Ⅰa,35 cases were in stage Ⅰb,29 cases were in stage Ⅱa,40 cases were in stage Ⅱb,27 cases were in stage Ⅲa,9 cases were in stage Ⅲb,and none were in stage Ⅲc,Ⅳa,or Ⅳb of TNM staging.MRI detected 176 positive cases,with 49 cases in stage Ⅰa,33 cases in stageⅠb,29 cases in stage ⅡIa,37 cases in stage Ⅱb,20 cases in stage Ⅲa,8 cases in stage Ⅲb,and 0 cases in stages Ⅲc,IVa,and Ⅳb of TNM staging.The diagnostic compliance rates of MRI for TNM staging(Ⅰa,Ⅰb,Ⅱa,Ⅱb,Ⅲa,Ⅲb,Ⅲc,Ⅳa and Ⅳb)of cervical cancer patients before treatment were 96.00%(48/50),94.29%(33/35),93.10%(27/29),87.50%(35/40),74.07%(20/27),88.89%(8/9),0,0 and 0.Conclusion MRI scanning of patients with suspected cervical cancer has high sensitivity,accuracy and specificity;meanwhile,MRI has higher diagnostic compliance rate for all stages of cervical cancer,MRI has significant effect in the diagnosis and pre-treatment staging of cervical cancer,which is worthy of popularization.
