OBJECTIVE: To evaluate the predictive value of three-dimensional (3D)-power Doppler sonography on recurrent @entity2208 . MATERIALS AND METHODS: The study @entity1 were divided into a recurrent @entity2208 group (30 cases) and a normal pregnancy group (21 cases). Measurement of endometrial thickness was performed using two-dimensional transvaginal ultrasound in the midluteal phase. The endometrial volume, vascularization index (VI), flow index (FI), and @entity455 ( @entity455 ) in midluteal and placenta volume, as well as the VI, FI, and @entity455 of early pregnancy were measured using Virtual Organ Computer-aided Analysis of 3D-power Doppler ultrasound. RESULTS: Endometrial thickness, endometrial volume, endometrial vascular data, VI, FI, and @entity455 of the midluteal phase were lower in the recurrent @entity2208 group compared with the normal pregnancy group (p  <  0.05). Placental volume, VI, and @entity455 during early pregnancy were lower in the @entity2208 group compared with the normal pregnancy group (p  <  0.05). There was no significant change in FI between the recurrent @entity2208 and control groups during early pregnancy (p  >  0.05). The predictive accuracy of endometrial thickness, endometrial volume, VI, FI, and @entity455 in the midluteal phase, and placenta volume, VI, FI, and @entity455 in early pregnancy as measured by the receiver operating characteristic curve to predict @entity2208 before 12 gestational weeks in @entity1 was 0.681, 0.876, 0.770, 0.720, 0.879, 0.771, 0.907, 0.592, respectively. CONCLUSION: The 3D-power Doppler ultrasound is a more comprehensive and sensitive method for evaluating endometrial receptivity. Endometrial volume, VI, FI, and @entity455 in the midluteal phase, as well as VI in early pregnancy, can be considered as predictive factors for recurrent @entity2208 .
