【摘要】 目的分析子宫内膜癌的MRI表现及分期,评价MRI在于宫内膜癌诊断及术前分期中的应用.方法回顾性分析35例经手术病理证实的子宫内膜癌患者术前均行MRI平扫及增强检查,在MRI上观察肿瘤信号特征、侵犯肌层的深度及肿瘤强化特点,根据FIGO分期原则进行分期,并与病理检查结果对比.结果子宫内膜癌的表现:子宫增大,子宫内膜弥漫性不规则增厚,在T1WI上大部份肿瘤信号与肌层信号相近,除非有出血致信号增高外常不易发现,T2WI上肿瘤呈相对高信号或等信号,结合带中断,增强后肿瘤呈中等度强化,强化程度低于子宫肌层.MRI对子宫内膜癌分期总的准确率为82.9%.结论MRI能多方位显示子宫内膜癌瘤灶、侵犯范围和深度,对子宫内膜癌的术前分期和肌层浸润定位方面有很高的应用价值.更多还原

【Abstract】 Objeetive To analyze the features of MRI and staging of endometrial carcinomat,and to evaluate the application of MRI in its diagnosis and preoperative staging.Methods Thirty-five patients with endometrial carcinoma proved by postoperative pathology were retrospectively reviewed.Before operation, all patients underwent conventional and contrast-enhanced MR scan.The signal features of the tumours and the depth of muscular invasion,and the enhancement features of the tumours were ovserved.MRI staging of endometrial carcinoma based on FIGO.35 cases of endometrial carcinoma was compared with the pathological findings. Results The MRI features of endometrial carcinoma included enlarged uterus,diffuse and irregular thickening in endometrium,moderate signal on T1WI and relative high signal on T2WI,interrupt junction zone,endometrial carcinoma showed moderate enhancement.The total accuracy of MRI for staging endometrial carcinoma was 82.9% .Conclusions MRI can clearly display the extent and depth of endometrial carcinoma from various directions.MRI has high a application value in preoperative staging and localization of myometrial invasion to endometrial car cinoma.更多还原
