The diagnostic value of magnetic resonance imaging in different planes for uterine septum malformation / 实用放射学杂志

ABSTRACT

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.
