title: [Polycystic ovaries--their ultrasonic diagnosis].
abstract: Polycystic ovaries are present like a two type: peripheral and cystic form. At the first cystic formations are disposed subcapsularis, at the second they are in the stromal zone. To have polycystic ovary syndrome the patient must have polycystic ovaries on (MI ultrasound and one or more of the following: oligo/amenorrhea, hirsutism/acne, raised LH:FSH ratio, higher of 2.5 or raised circulation androgens. The LH:FSH ration is higher in patient--with peripheral form. The basal morphological changes for estimation of the ovarian structure are: doubly ovarian volume, approximately in 50%, increased in number of atretic follicules, 30% increased the cortical stroma and five enlarging of the medullar stroma. Early Doppler studies have demonstrated increased stromal vascularity if correlated with raised LH/FSH ratio and raised androgens level. It was found increased impedance in uterine artery and decreased of PI (pulsatility index). There are difference between patient with peripheral and cystic form on Doppler examinations. In the first group have lower pulsatility index in the ovarian artery, higher stromal vascularity and LH/FSH ratio and increased score 2. All present results of investigations determine the criteria to present ovarian structure in context of PCOS as using conventional and Doppler ultrasonographic.
