目的：探讨磁共振不同平面成像在子宫纵隔诊断中的应用价值。方法回顾分析本院28例经宫腔镜手术诊断为先天性子宫纵隔畸形患者的 MRI 图像，比较 MRI 不同平面成像对子宫纵隔的显示情况。结果磁共振不同平面成像对28例先天性子宫纵隔畸形的显示，斜冠状位的敏感度不仅高于常规轴位和斜轴位，而且高于常规冠状位(P <0.05)。斜冠状位是诊断子宫纵隔最敏感的 MRI 成像方位，尤其是对完全性子宫纵隔畸形的诊断。斜冠状位 T2 WI 能在同一层面全面直观地显示子宫纵隔的异常形态和信号特征。斜轴位 T2 WI 可显示子宫纵隔的连续断面图像，对子宫纵隔的诊断起到补充作用。矢状位对子宫纵隔的显示欠佳。结论 MRI 斜冠状位与斜轴位结合可明确显示子宫纵隔。

Objective To explore the value of magnetic resonance imaging (MRI)different planes in the diagnosis of uterine sep-tum.Methods The MR images of 28 cases with hysteroscopy surgery proved congenital uterine septum were analyzed retrospective-ly.The MRI findings in different planes of uterine septum were compared.Results 28 cases of congenital uterine septum malforma-tion were shown by magnetic resonance imaging in different planes.The sensitivity of oblique coronal for the uterine septum was not only higher than the conventional axial and oblique axial,but also higher than normal coronal (P <0.05).The oblique coronal was the most sensitive MRI imaging position for diagnosis of uterine septum,especially for complete uterine septum malformation.The uterine septum morphology and signal characteristics was fully visualized and accurately measured by the oblique coronal T2 WI.The oblique axial T2 WI displayed a continuous cross-sectional image of uterine septum and played a complementary role on the diagnosis of uterine septum.In contrast,a poor display was observed for uterine septum on sagittal plane.Conclusion Congenital uterine sep-tum can be clearly demonstrated by MRI oblique coronal and oblique axial joint application.
