A comparative study of different ultrasonic imaging modalities in the diagnosis of congenital uterine malformation

Abstract

Objective To discuss the accuracy of 2D ultrasonography (2D-US) and 3D ultrasonography (3D-US, Render mode and Omni view mode) in diagnosing congenital uterine malformation, and explore a more suitable ultrasonic examination method for clinical practice. Methods One hundred and fifty-nine patients with suspected uterine malformation had been examined by 2D-US and 3D-US in Obstetrics and Gynecology Hospital of Fudan University from September 2011 to January 2013. Uterine coronal plane was reconstructed and measured by two 3D-US imaging modes respectively. Then qualitative diagnosis and categorization was done. The diagnostic accuracy of the 2D-US and 3D-US was compared according to the results of hysteroscopy, hysteroscopy combined with laparoscope, hysterosalpingography (HSG) or magnetic resonance imaging (MRI). Results In comparison with the results of hysteroscopy, hysteroscopy combined with laparoscope, HSG or MRI, the diagnostic accuracy of 3D-US Render mode (78.6%, 125/159) and Omni view mode (81.8%, 130/159) was higher than 2D-US (52.8%, 84/159). There was statistical difference between 2D-US and 3D-US imaging modes (Render mode: χ2=23.465, P<0.01, Omni view mode: χ2=30.234, P<0.01) in diagnostic accuracy of congenital uterine malformation. Conclusions 3D ultrasonography is more accurate than 2D ultrasonography in diagnosing congenital uterine malformation. Both of Omni view and Render imaging mode can be used for the diagnosis of uterine malformation.
