Abstract: To evaluate the application of intracavitary three-dimensional ultrasonography in the diagnosis of polycystic ovary syndrome ( PCOS). The three-dimensional volumes of ovary were measured by intracavitary ultrasonography in 40 PCOS patients and 40 normal controls. The diagnostic value of parameters derived from three-dimensional ultrasonography was evaluated by using the receiver operating characteristic (ROC) curve. The ovarian volume, stromal volume, and the stromal/total volume ratio in PCOS group were significantly higher than those in control group (both P ＜ 0. 05 ) ; the area under ROC curve ( AUC ) of them were 0. 876, 0. 926, 0. 886 respectively. Among these parameters, stromal volume had the highest diagnostic value for PCOS, the cut-off value of which was 7.52 cm3 with a sensitivity of 88% and a specificity of 90%. Volume parameters of ovary measured by intracavitary three-dimensional ultrasonography can offer quantitative information for the diagnosis of PCOS.
