目的 探讨MRI在宫颈癌患者术 前临床分期和盆腔淋巴结转移诊断中的 应用价值。方法 将2012年9月至2014年 6月来我院接受治疗的宫颈癌患者120例 纳入本研究。对患者进行MRI扫描。观察 患者术前MRI分期、术前临床分期及术后 病理分期情况。结果 术前临床分期和术 后病理分期对比差异无统计学意义（P ＜0.05）；术前临床分期和术前MRI分期 对比，差异无统计学意义（P＜0.05）； 术后病理分期和术前MRI分期对比，差异 无统计学意义（P＜0.05）。宫颈癌深肌 层浸润手术前MRI诊断灵敏度为85.7%，特 异度为98.1%。宫颈癌阴道受累手术前MRI 诊断灵敏度为95.7%，特异度为97.4%。 宫颈癌旁浸润手术前MRI诊断灵敏度为 95.0%，特异度为90.1%。宫颈癌淋巴结转 移手术前MRI诊断灵敏度为81.8%，特异度 为96.1%。结论 MRI在宫颈癌患者术前临 床分期和盆腔淋巴结转移中的诊断价值较 高，值得临床推广。

Objective To explore the values of preoperative clinical staging and pelvic lymph node metastasis for cervical cancer diagnosis by MRI. Methods One hundred and twenty-two cases of patients with cervical cancer were researched. They were scanned by MRI. The MRI classification, clinical stages, pathological stage were observed. Results It was significant different between the clinical stages and pathological stage(P＜0.05), the MRI classification and clinical stages had significant difference (P＜0.05). There was no significant difference on the MRI classification and pathological stage(P＞0.05). The diagnostic sensitivity of MRI for cervical cancer infiltration degree of muscle layer was 85.7% and the specificity was 98.1%. The diagnostic sensitivity of MRI for cervical cancer vagina involvement was 95.7% and the specificity was 97.4%. The diagnostic sensitivity of MRI for cervical cancer infiltration was 95.0%, specificity was 90.1%. The diagnostic sensitivity of MRI for cervical lymph node metastasis was 81.8% and the specificity was 96.1%. Conclusion MRI has high values of preoperative clinical staging and pelvic lymph node metastasis for cervical cancer diagnosis, which deserves the clinical expansion.
