摘　　要：目的:探讨子宫内膜癌的MRI表现特点,提高该病的诊断及鉴别诊断水平。方法:回顾性分析56例经手术病理证实的子宫内膜癌的临床资料及MRI表现。56例均行MRI平扫、增强扫描及DWI。结果:56例MRI平扫多表现为T1WI呈等信号,T2WI呈略高信号;动态增强扫描肿瘤呈轻度渐进性强化,信号强度始终低于明显强化的外肌层;DWI呈高信号,ADC呈低信号,ADC值平均为(0.904±0.185)×10^-3mm/s。结论:MRI能准确预测子宫内膜癌浸润肌层深度、宫颈侵犯、淋巴结和远处转移。Objective:To explore MR features of endometrial carcinoma and improve the level of diagnosis and differential diagnosis of the disease.Methods:Clinical data and MR findings of 56 cases with endometrial carcinoma confirmed by pathology were retrospectively analyzed,56 cases were examed by MRI plain,enhanced MRI and DWI.Results:Of the 56 cases with endometrial carcinoma,the plain scan mostly showed an equal T1 and slightly longer T2 signal,while the dynamic enhancement tumors showed slight gradual enhancement,the signal intensity was always lower than that of the obviously enhanced outer muscle layer,DWI showed high signal,ADC showed low signal,and the ADC value averaged(0.904±0.185)×10^-3 mm/s.Conclusion:MRI can accurately predict the depth of infiltrating myometrium,invasion of cervical matrix,lymph node involvement and distant metastasis.
