| 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。 |

| Abstract：［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. |
