目的：探讨卵巢卵泡膜细胞瘤的 MR 动态增强扫描（DCE）与扩散加权成像（DWI）表现特征，提高其正确诊断率。方法：回顾性分析经病理检查证实的30例卵巢卵泡膜细胞瘤的 MRI 影像资料，分析肿瘤的 MRI 表现，尤其是DCE 及 DWI 特征。结果：30例肿瘤 MRI 平扫 T1 WI 呈等或稍低信号，T2 WI 呈等或稍高信号，T2 WI 抑脂序列呈高信号；所有病例 DWI 均呈高-稍高信号，ADC 值范围为（1．182±0．65）×10－3 mm2／s；动态增强扫描中24例病灶为 I 型曲线，6例为 II 型曲线；所有病灶第一分钟强化率为86．64％～87．99％，与正常卵巢对比，两者之间差异有统计学意义。结论：卵泡膜细胞瘤具有一定的 MRI 表现特征，结合 DCE 及 DWI 的特征能对诊断提供很大帮助。

Objective:To investigate dynamic contrast enhanced (DCE)MRI and diffusion weighted MR imaging (DWI)characteristics of ovarian thecoma,so as to improve the rate of correct diagnosis.Methods:The MR image data of 30 patients with pathologically proved ovarian thecoma were analyzed retrospectively and the MRI manifestations especially the DCE and DWI features of tumor were analyzed.Results:In 30 cases of the tumor,MRI plain scan showed isointensity or hy-pointensity on T1 WI,isointensity or hyperintensity on T2 WI,hyperintensity on fat-suppressed T2 WI,and hyperintensity or slight hyperintensity on diffusion weighted imaging (DWI)in all cases,and the range of ADC value was (1.182±0.65)× 10 -3 mm2/s.24 lesions showed type Ⅰ curve in DCE scanning and 6 lesions showed type Ⅱ curve.The enhancement rate in the first minute in all lesions was 86.64 ~ 87.99%,which had statistic difference when it was compared with normal oyaries.Conclusion:MRI manifestations of ovarian thecoma have certain characteristics,the diagnosis accuracy of MRI can be improved when MRI combined with DCE and DWI features.
