摘 要: | 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。

Abstract: | 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. |
