目的 探讨MRI检查对于宫颈癌分 期、宫旁浸润和淋巴结转移的诊断价值。 方法 选取来我院就诊的84名确诊为宫颈 癌的患者作为研究对象，通过对比MRI分 期、临床分期以及手术病理分期来判断 MRI分期在宫颈癌分期的准确性，以及判 断宫旁转移和淋巴结转移的价值。结果 MRI对于宫颈癌分期的准确率为82.1%； MRI对于判断宫旁转移的灵敏度为78.3%， 特异度为95%，准确率为90.5%；MRI对于 判断淋巴结转移的灵敏度为83.3%，特异 度为97.0%，准确率为82.1%。结论 MRI宫 颈癌分期优于临床分期，且在判断宫旁转 移和淋巴结转移方面有独特的优势，值得 临床上广泛推广。

Objective To evaluate the value of MRI in evaluating the staging of cervical cancer and parametrial invasion and lymph node metastasis. Methods 84 patients with biopsy-confirmed cervical cancer were selected as a research object. By contrast MRI staging, clinical staging and surgical staging to determine the accuracy of MRI staging in cervical cancer staging, and determine the value of parametrial invasion and lymph node metastasis. Results The accuracy of MRI staging was 82.1%. The sensitivity, specificity and accuracy of MRI in judging parametrial invasion were 78.3%, 95%, 90.5% respectively. The sensitivity, specificity and accuracy of MRI in judging lymph node metastasis were 83.3%, 97.0%, 82.1% respectively. Conclusion MRI cervical cancer staging is superior to the clinical stage. MRI cervical cancer staging has a unique advantage in judging parametrial invasion and lymph node metastasis. It should be widely applied.
