To determine the role of three-dimensional (3D) power Doppler imaging in the diagnosis of polycystic ovary syndrome (PCOS).
Pulsatility index (PI) and resistance index (RI) of the uterine artery and ovary were measured by two-dimensional (2D) Doppler imaging, while vascularization index (VI), flow index (FI), and vascularization flow index (VFI) were measured by 3D power Doppler in 25 patients with PCOS and 25 women with normal menstrual cycles used as a control group.
Uterine artery PI and RI were significantly higher (P<0.001) and ovarian PI and RI were significantly lower (P<0.001) in women with PCOS compared with controls. Ovarian VI and VFI were significantly higher in women with PCOS compared with the control group (P<0.001).
3D power Doppler indices were higher in women with PCOS than in the control group and were positively correlated with 2D color Doppler indices, and clinical and hormonal parameters. High 3D power Doppler indices may be useful as one of the diagnostic criteria for PCOS.
确定三维（3D）能量多普勒成像在多囊卵巢综合征（PCOS）诊断中的作用。
采用二维（2D）多普勒成像测量25例PCOS患者和25例月经周期正常的女性（作为对照组）子宫动脉和卵巢的搏动指数（PI）及阻力指数（RI），同时采用三维能量多普勒测量血管化指数（VI）、血流指数（FI）和血管化血流指数（VFI）。
与对照组相比，PCOS患者子宫动脉PI和RI显著升高（P<0.001），卵巢PI和RI显著降低（P<0.001）。与对照组相比，PCOS患者卵巢VI和VFI显著升高（P<0.001）。
PCOS患者的三维能量多普勒指标高于对照组，且与二维彩色多普勒指标、临床及激素参数呈正相关。高三维能量多普勒指标可能作为PCOS的诊断标准之一。
