目的 探讨子宫平滑肌瘤的MRI表现及其诊断价值。方法 全部病例均行MRI及超声检查。结合手术病理结果回顾性分析 32例 ( 71个病灶 )子宫平滑肌瘤的MRI表现 ,并与超声检查相对比。结果 所有病灶MRI均表现为T1WI中等或略低信号 ;T2 WI低信号 ,退变型肌瘤夹杂有斑片状高信号 ,肿瘤边界清楚 ,瘤周大多可见包膜 ( 5 5 / 71)。对发现 <2cm的肿瘤、判断肿瘤变性及肿瘤的定位MRI均优于超声检查。结论 子宫平滑肌瘤MRI表现颇具特征性 ,较B超检出率更高 ,可获得更精确的资料 ,对制定治疗方案及随访观察肿瘤的变化具有较大的临床意义
Objective To investigate the MRI findings of uterine leiomyomas and its diagnostic value. Methods All cases underwent MRI and ultrasound. The MRI findings of 32 cases (71 lesions) of uterine leiomyoma were analyzed retrospectively with the results of surgical pathology and compared with those of ultrasound. Results All MRI images showed moderate or low T1WI signals. T2WI low signal and degenerative myoma were mixed with patchy hyperintensities, and the tumor boundary was clear. Most of the tumors showed envelopment (55/71). Found <2cm of the tumor, to determine the tumor degeneration and tumor localization MRI are superior to ultrasound. Conclusions The manifestations of uterine leiomyoma are quite characteristic of MRI, with a higher detection rate than B-type ultrasonography, more accurate data can be obtained, which is of great clinical significance for formulating treatment plan and observing the change of tumor in follow-up
