摘　　要：目的:探讨磁共振检查方法对子宫内膜间质肉瘤的诊断价值。方法:回顾性分析8例经手术后病理证实为子宫内膜间质肉瘤的MRI图像特征。结果:总共8例子宫内膜间质肉瘤,均为低级别,3例发生在宫腔内,4例发生在肌壁间,1例同时发生于宫腔、宫体。与正常子宫肌层相比,以上病变在MRI上均表现为T1W呈等、低信号为主,T2W呈以稍高信号为主的混杂信号,DWI上均呈高信号,且伴有ADC值显著降低,增强后呈不均匀强化改变,强化程度稍弱于正常子宫肌层。结论:根据MRI图像上的特征性表现,可以提高子宫内膜间质肉瘤的诊断率,减少其误诊率。Purpose: To investigate the value of MRI for the diagnosis of endometrial stromal sarcoma (ESS). Methods: Eight cases of ESS, which were proved with histopathological results, were involved in this study. The image features of them were analyzed. Results: All of the 8 ESS cases were low grade. Three of them located in the uterine cavity, 4 of them located in the intramural, and 1 cases involved both the uterine cavity and the intramural. The signals of lesions were quite different from the intramural, which were low intensity signal on the T1WI, high and heterogenous intensity signal on T2WI, obviously high intensity signal on DWI, and the lesions were with slight enhancement on post contrasted images. Conclusion: MRI is useful for differentiating ESS from other benign lesion, DWI was the most effective one than other MRI sequences.
