目的探讨磁共振扩散加权成像 (DWI)联合经阴道超声(TVUS)对早期宫颈 癌的诊断效果。方法 就2008年10月到 2013年2月于本院住院的拥有完整影像学 检查相关资料的80名宫颈癌病人，其中临 床分期有ⅠB与ⅡA期，且术前无其他治 疗史，对80名病人术前进行DWI和TSUS检 查，回顾分析影像学检查结果与术后病理 的关系。结果 预测肿瘤直径、宫颈间质 浸润、淋巴结遭到牵连的精确度：DWI结 果分别是81.29%、73.32%和83.99%；TVUS 分别为66.67%、50.90%和78.67%；DWI联 合TVUS分别为84.00%、77.87%、89.33%， 对ⅠB期和ⅡA期宫颈癌的临床分期与术后 再分期的总准确率为76.32%。结论 术前 DWI联合TVUS检查可以很好的对早期宫颈 癌有可能产生的预后高危要素的原因进行 预测和参考，能够增强对术前病情进行评 估的精确度，在今后的治疗过程中可以对 治疗方案进行更好的选择。

Objective To explore the value of the diffusion weighted DWI united with TVUS in the diagnosis of early cervical cancer. Methods To select eighty cervical cancer patients from Sep. 2008 to Jan. 2013 in our hospital who were grouped into clinical staging of I B and II A period, without any other preoperative treatment. The eighty cases received DWI and TSUS examination, and finally take a retrospective analysis of the relationship between the imaging findings and postoperative pathology. Results The prediction of tumor diameter, cervical stromal invasion, lymph node involvement in accuracy rate: DWI were 81.33%, 73.33% and 84%; TVUS were 66.67%, 50.90% and 78.67%; DWI combined with TVUS were 84%, 77.87%, 89.33%, cervical cancer for clinical stage I B and II A stage and postoperation re-staging accuracy is 76.32%. Conclusion The high risk factors for predicting prognosis may appear early cervical cancer, preoperative DWI combined with TVUS examination has important value on improving the preoperative condition assessment accuracy, and providing the reference for the selection of the best therapeutic scheme.
