目的探讨磁共振成像(MRI)在 先天性双角子宫畸形诊断中的价值。方 法 回顾性分析13例磁共振成像诊断为双 角子宫畸形的MRI表现及临床资料，比较 不同扫描方位对双角子宫畸形的显示情 况，并与宫腔镜检查及手术结果进行对 照。结果 MRI诊断结果与宫腔镜检查及 手术结果相符12例，MRI诊断先天性双角 子宫畸形的准确率为92.3%，其中斜冠状 位诊断13例，横轴位诊断8例，矢状位上 不能做出明确定性诊断。结论 MRI可以 直观显示宫腔结构和宫底外观形态,且能 获得精确的量化分析结果,是先天性双角 子宫畸形定性和定量诊断的最佳无创性 检查方法；MRI对先天性双角子宫畸形诊 断准确率高，斜冠状位T2WI像结合轴位 T2WI像是最佳检查方位。

Objective To investigate value of the magnetic resonance imaging (MRI) in the diagnosis of congenital double angular deformity of uterus. Methods Retrospective analysis MRI findings and clinical data from 13 cases with double angular deformity of uterus , different scanning positions of MRI on bicornuate uterus malformation were compared, and compared with hysteroscopy and operation results. Results MRI results was consistent with hysteroscopy and operation results in 12 cases, the accurate rate of congenital double angular uterine malformation diagnosis of MRI was 92.3%, 13 were diagnosed with oblique coronal, axial diagnosis in 8 cases, the sagittal cannot make a clear diagnosis. Conclusion MRI is the best noninvasive method to congenital uterine malformation of double angle in qualitative and quantitative diagnosis because it can directly display the uterine cavity structure and the fundus appearance and can obtain accurate analysis of quantitative; MRI has high accuracy in the diagnosis of congenital uterine malformation of double angle, and oblique coronal T2WI imaging combined with axial T2WI is the best check position.
