Abstract
To determine the role of 3-dimensional power Doppler and color Doppler imaging in the diagnosis of polycystic ovary syndrome (PCOS). Cross sectional study. Twenty five diagnosed patients of PCOS formed the study group. Twenty five normal menstruating women comprised the control group. Color Doppler of the uterine artery and ovary was performed to calculate pulsatility index (PI) and resistance index (RI). 3D power Doppler imaging of the ovary was performed and Vascularisation index (VI), Flow index (FI) and Vascularisation flow index (VFI) were calculated using a software histogram. Uterine artery PI and RI were increased in PCOS group compared to controls (p < 0.001). PI and RI of the ovary were decreased significantly in the PCOS group compared to controls (p < 0.001). VI (6.07 & 1.87 in cases and controls respectively) and VFI (2.39 & 1.16 in cases and controls respectively) of the ovary were significantly increased in PCOS group compared to controls (p < 0.001). FI of the ovary was increased in PCOS group but not to a significant level. 3D power Doppler and 2D Doppler indices may be used as one of the criteria to diagnose PCOS.
