| 摘 要： | 目的：探讨磁共振扩散加权像（DWI）及表观扩散系数对卵巢表皮样囊肿的诊断价值。方法回顾性分析11例经手术病理证实的卵巢表皮样囊肿患者磁共振常规及扩散加权成像，选取感兴趣区，测量表观扩散系数进行分析。结果磁共振平扫11例T1WI呈低信号，T2WI为高信号，DWI呈高信号，表观扩散系数（ADC）值降低，ADC值范围为（0．632~1．082）×10-3 mm2/s。结论通过对卵巢表皮样囊肿磁共振表现的分析，提示扩散加权成像对卵巢表皮样囊肿诊断有一定特异性。

| Abstract: | Objective To study the value of diffusion-weighted MR imaging（DWI） and apparent diffusion coeffi-cient（ADC） in the diagnosis of ovarian epidermoid cyst. Methods The MRI and DWI data of 11 cases with ovarian epidermoid cyst confirmed by surgery and pathology were analyzed retrospectively. Results All 11 cases were demonstrated as hypointensity on T1 weighted imaging （T1WI） and hyperintensity on T2 weighted imaging （T2WI） and DWI, and the ADC value was reduced, with the range of （0.632~1.082）×10-3 mm2/s. Conclusion Ovarian epidermoid cyst analyzed by the MRI and DWI has some characteristics which contributes to the clinical diagnosis of ovarian epidermoid cyst. |
