摘要
[目的]探讨磁共振成像(MRI)在宫颈癌诊断及其分期中的应用价值。[方法]对84例经宫颈活检确诊为宫颈癌的患者在手术前进行临床分期,并在术前2周内进行MRI检查。参照FIGO制订的标准,以病理结果作为诊断金标准,将临床分期和MRI分期分别与术后病理结果进行比较分析,以评价宫颈癌术前MRI的诊断价值。[结果]84例宫颈癌患者临床分期准确率为61.90%,对Ⅱb期诊断准确率、灵敏度和特异性分别为73.81%、47.06%、80.6%。根据MRI检查结果分期,准确率为86.90%,对Ⅱb期诊断准确率、灵敏度和特异性分别为91.69%、76.47%、95.52%。MRI诊断淋巴结转移准确率、灵敏度和特异性分别为84.52%、80.00%、85.14%。[结论]宫颈癌术前行MRI检查可多方位成像清楚显示宫颈肿瘤的病变范围,提高了分期的准确性,对淋巴结转移和宫旁受累有较好的诊断价值。
[Purpose] To evaluate the application value of magnetic resonance imaging（MRI）in the diagnosis and clinical staging for cervical cancer. [Methods] A total of 84 cases with cervical cancer diagnosed by cervical biopsy were staged pre-operation and examined by MRI 2 weeks before operation. According to FIGO standards and with pathology as golden standard for diagnosis,clinical and MRI staging were compared with post-operative pathology to evaluate the diagnostic value of MRI pre-operation in cervical cancer.[Results] The diagnostic accuracy of clinical staging was 61.9%,and the accuracy,sensitivity and specificity for stage Ⅱb were 73.81%,47.06% and 80.6% respectively. The diagnostic accuracy of MRI staging was 86.9%,and the accuracy,sensitivity and specificity for stage Ⅱb were 91.69%,76.47% and 95.52% respectively. The accuracy,sensitivity and specificity of MRI diagnosis for lymph node metastasis were 84.52%,80.00% and 85.14% respectively. [Conclusions]MRI could clearly reveal cervical cancer invasion by multiple imaging,and might improve the accuracy of staging,and has diagnostic value for lymph node metastasis and parametrial infiltration.
