Abstract Objective: To evaluate the application value of the combination of transvaginal two-dimensional ultrasound(2D-TVS), three-dimensional ultrasound(3D-TVS) volume imaging and power Doppler ultrasound(3D-PDUS) in the diagnosis of intrauterine adhesions(IUA). Methods: 89 females suspected with intrauterine adhesions were examined separately with 2D-TVS, 3D-TVS, 3D-PDUS. Ultrasound parameters were recorded respectively, including endometrial thickness(ED), endometrial volume(EV) and vascularization index(VI), flow index(FI) and vascularization-flow index(VFI). According to the hysteroscopy(HS), the patients were divided into normal group, mild adhesion group, moderate adhesion group and severe adhesion group. The ultrasonic accuracy and image characteristics of IUA were analyzed, and the varieties of the ultrasound parameters were compared among four groups retrospectively. Results: The sensitivity, specificity, Youden index of the combination of 2D-TVS and 3D-TVS in the diagnosis of intrauterine adhesions were 91.8%, 87.5%, 0.793, and the diagnostic accordance rate with HS was 91.0%. Indicators EV of each group had statistical significance(all P＜0.05). ED, VI and VFI were significant different between the normal group and mild, moderate, severe adhesion groups, as well as between mild and severe adhesion groups(all P＜0.05). Conclusion: The combination of 2D-TVS, 3D-TVS volume imaging and 3D-PDUS can provide more accurate, direct and comprehensive diagnostic information for intrauterine adhesions，which has high clinical practical value.
