摘要
目的 分析子宫肌瘤与子宫腺肌病的MRI表现特点 ,评价MRI在两病鉴别诊断中的价值。方法 回顾性分析 6 6例经手术病理证实的子宫平滑肌瘤和子宫腺肌症患者MRI资料 ,仔细观察两病在T1 W、T2 W、STIR及增强后T1 W像上的表现。结果 MRI对两病诊断的敏感性为 1 0 0 %,诊断符合率为 91 .7%。两种病变的T1 WI信号、边界、T2 WI上病灶周围的改变、病侧子宫内膜以及临近结合带的改变方面具有较大差异 ;而在子宫形态、T2 WI信号特点及增强特点上并没有明显差别 ;T2 WI及STIR图像对病灶的显示最清晰。结论 子宫肌瘤和子宫腺肌病由于病理基础不同 ,MRI表现也各有不同 ;选择合适的MRI检查序列与方法对两病鉴别诊断具有重要的价值。
Objective To analyze the MRI features of uterine leiomyomas and adenomyosis,and to evaluate the value of MRI in differential diagnosis between two diseases.Methods The MR imaging data of 66 cases with uterine leiomyomas or adenomyosis proved by surgical and pathological findings were retrospectively analyzed.The appearances of two diseases on T1W、T2W、STIR and enhanced T1W imagings were carefully investigated.Results MRI diagnostic sensitivity of two diseases was 100%,the coincidence rate of diagnosis was 91.7%.The differences on T1WI、changes on border、peripheral changes on T2WI、and changes in endometrium and at junctional zone were distinctive,whereas the differences of uterine deformation、T2WI and enhanced imagings were indistinctive.The lesions could be clearly displayed on T2W and STIR imagings.Conclusion As the result of different pathology,leiomyomas and adenomyosis have different exhibition on MR imagings.It's very important to choose appropriate MRI sequences and techniques.
