摘　　要：目的探讨宫颈癌多模态磁共振成像(Magnetic Resonance Imaging,MRI)对国际妇产科协会(Federation International of Gynecology and Obstetrics,FIGO)分期和淋巴结转移的评估价值。方法选取80例宫颈癌患者,均接受常规MRI序列扫描、弥散加权成像扫描、动态对比增强MRI扫描的多模态MRI检查,以病理检查结果为金标准,判断多模态MRI检查对FIGO分期和淋巴结转移的评估价值。结果病理检查结果显示,FIGO分期Ⅰ、Ⅱ、Ⅲ、Ⅳ期的分别有21、35、14、10例,共110个淋巴结转移。多模态MRI检查结果显示,FIGO分期Ⅰ、Ⅱ、Ⅲ、Ⅳ期的分别有20、38、12、10例,多模态MRI检查诊断Ⅳ期宫颈癌的敏感度、特异度、准确度为100.00%,高于Ⅰ、Ⅱ、Ⅲ期宫颈癌(P<0.05)。多模态MRI检查发现104个淋巴结转移,其评估淋巴结转移的敏感度、特异度、准确度为94.55%、91.53%、92.98%。结论多模态MRI检查对宫颈癌FIGO分期和淋巴结转移具有较高评估价值,可作为宫颈癌术前分期和淋巴结转移评估的重要手段。Objective To investigate the value of multimodal MRI for the assessment of federation international of gynecology and obstetrics(FIGO)staging and lymph node metastasis in cervical cancer.Methods A total of 80 cases of cervical cancer patients were selected and all underwent multimodal MRI examinations with conventional MRI sequence,diffusion weighted imaging scan,and dynamic contrast-enhanced MRI scan.Taking the pathological examination results as the standard,the value of multimodal MRI for FIGO staging and lymph node metastasis was judged.Results Pathological examination results showed that there were 21,35,14 and 10 cases of FIGO stageⅠ,Ⅱ,Ⅲ,andⅣ,respectively,with 110 lymph node metastases.Multimodal MRI showed that there were 20,38,12 and 10 cases of FIGO stageⅠ,Ⅱ,Ⅲ,andⅣ,respectively.The sensitivity,specificity and accuracy of multimodal MRI in the diagnosis of stageⅣcervical cancer were 100.00%,which were higher than that of stageⅠ,Ⅱ,andⅢcervical cancer(P<0.05).Multimodal MRI examination found 104 lymph nodes metastasis,and the sensitivity,specificity and accuracy of evaluating lymph node metastasis were 94.55%,91.53%and 92.98%.Conclusion Multimodal MRI has a high evaluation value for the FIGO staging and lymph node metastasis of cervical cancer,and it can be used as an important method for the evaluation of preoperative staging and lymph node metastasis of cervical cancer.
