目的 探讨MRI检查对宫颈癌阴道 受累及淋巴结转移的诊断价值。方法 回 顾性分析我院2016年1月至2017年1月收 治的60例宫颈癌患者临床资料，宫颈癌 均经手术病理证实，所有患者均行术前 MRI检查和手术治疗，以术后病理结果为 金标准，将MRI检查对阴道受累、淋巴结 转移和国际妇产科联盟(FIGO)分期判断 结果与其进行比较，分析MRI检查在阴道 受累、淋巴结转移和FIGO分期方面的诊 断价值。结果 ①MRI诊断阴道受累的灵 敏度、特异度和准确度依次为75.00%、 92.31%、90.00%；误诊率和漏诊率依次为 7.69%和25.00%。②MRI诊断淋巴节转移的 灵敏度、特异度和准确度依次为76.92%、 97.87%、93.33%；误诊率和漏诊率依次为 2.13%和23.08%。③与病理结果相比，临 床分期总体准确度为68.33%，MRI分期总 体准确度为85.00%，临床分期总体准确度 与MRI分期差异显著(P<0.05)。结论 MRI 对宫颈癌阴道受累及淋巴结转移具有重要 诊断价值，可以提高临床FIGO分期诊断准 确率。

Objective To investigate the value of MRI examination in the diagnosis of vaginal involvement and lymph node metastasis of cervical cancer. Methods The clinical data of 60 patients with cervical cancer treated in our hospital from January 2016 to January 2017 were retrospectively analyzed, and cervical cancer was confirmed by surgery and pathology. All patients underwent preoperative MRI examination and surgical treatment. With postoperative pathological results as the golden standard, results of MRI in the diagnosis of vaginal involvement, lymph node metastasis and the International Federation of Gynecology and Obstetrics (FIGO) stage were compared. The value of MRI in the diagnosis of vaginal involvement, lymph node metastasis and FIGO stage was analyzed. Results ①The sensitivity, specificity and accuracy of MRI in the diagnosis of vaginal involvement were 75.00%, 92.31% and 90.00%, respectively. The misdiagnosis rate and missed diagnosis rate were 7.69% and 25.00% respectively. ②The sensitivity, specificity and accuracy of MRI in the diagnosis of lymph node metastasis were 76.92%, 97.87% and 93.33%, respectively. The misdiagnosis rate and missed diagnosis rate were 2.13% and 23.08% respectively. ③Compared with the pathological results, the overall accuracy rates of clinical staging and MRI staging were 68.33% and 85.00%, respectively, with a significant difference (P<0.05). Conclusion MRI is of great value in the diagnosis of vaginal involvement and lymph node metastasis of cervical cancer, and it can improve the accuracy of clinical FIGO staging.
