DWI结合高分辨T_2WI磁共振在子宫内膜癌分期中的价值

目的:探讨DWI结合高分辨T2WI在子宫内膜癌分期中的价值。方法:回顾性分析70例经手术病理证实的子宫内膜癌DWI及高分辨T2WI表现,测量其ADC值,判断其浸润范围,并与术后病理结果相比较。结果:DWI结合高分辨T2WI对子宫内膜癌2009FIGO分期准确性为94.3%,评价浅肌层、深肌层浸润的敏感度、特异度和准确度分别为94.5%、82.4%、94.3%和83.3%、95.3%、94.3%;评价子宫内膜癌宫颈基质浸润的敏感度、特异度和准确度分别为100%、100%和100%。结论:DWI结合高分辨T2WI磁共振能够提高子宫内膜癌浸润深度评价的准确度,有助于子宫内膜癌的诊断、分期及帮助制定治疗计划。

Evaluation of diffusion weighted imaging and high resolution T2-weighted MR imaging in staging endometrial cancer

Objective： To evaluate the aging （T2 WI） in staging endometrial cancer. Methods：The features of DWI and high resolution T2 WI in 70 patients with endome- trial cancer confirmed pathologically and surgically were retrospectively reviewed. ADC value and invasive extent were eval- uated and compared with pathologic findings. Results： The accuracy of DWI and high resolution T2 WI in the staging of endo- inertial carcinoma using the 2009 FIGO staging system were 94.3 % （66/70）. The sensitivity, specificity and accuracy of as- sessing superficial myometrial invasion and deep myometrial invasion were 94. 5%, 82.4%, 94.3% and 83.3%, 95.3%, 94.3 % ,respectively. The sensitivity, specificity and accuracy of assessing cervical stroma invasion were： 100Y00,100% and 100 %, respectively. Conclusion： The combination of DWI and high resolution T2 WI can increase accuracy for predicting the invasive extent of endometrial cancer which is helpful in the diagnosis,preoperative staging,and treatment plans.
