摘　　要：目的探讨磁共振常规及弥散加权成像在宫颈癌淋巴结转移诊断中的敏感性、特异性。方法 113例IB1至IIB期宫颈癌患者行术前MRI常规及弥散加权成像检查、根治性子宫切除术加盆腔或盆腔及腹主动脉旁淋巴结清扫术。结果 94例(83.2%)经术后病理学检查证实无淋巴结转移,19例(16.8%)有淋巴结转移。MRI常规及弥散加权成像判断宫颈癌淋巴结转移的敏感性为68.4%(13/19),特异性为96.8%(91/94),预测准确性为92.0%(104/113)。结论磁共振常规及弥散加权成像对宫颈癌淋巴结转移的预测准确性较高。Objective To investigate the sensitivity and specificity of conventional magnetic resonance imaging（MRI） and diffusion weighted imaging（DWI） in diagnosis of lymph node metastasis in cervical cancer.Methods A total of 113 patients with IB1 to IIB stage cervical cancer underwent conventional MRI and DWI,and radical hysterectomy plus pelvic and/or paraaortic lymph node dissection.Results Pathological examination showed that lymph node metastases occurred in 19 cases（16.8%）.The sensitivity,specificity,and accuracy of conventional MRI and DWI for determining lymph node metastasis in cervical cancer were 68.4%（13/19）,96.8%（91/94）,and 92.0%（104/113）,respectively.Conclusion There is a high predictable accuracy of conventional MRI and DWI for determining lymph node metastasis in cervical cancer.
