Background: Polycystic ovarian syndrome (PCOS) is a common endocrine disorder of premenopausal (1) women affecting approximately 5-10% of female population in their reproductive years . The clinical, biochemical as well as the radiological spectrum of PCOS and their correlations have gained importance over the years owing to complex pathophysiology of this syndrome, which still remains partially understood. Aims & Objectives: To study hemodynamic changes in ovarian and uterine arteries in PCOS patients using color doppler ultrasound, along with their clinical and biochemical parameters. A total of 60 patients with clinical history of infertility Methods: (30 obese & 30 non-obese) and 30 control (fertile women) were taken, who underwent transvaginal ultrasound and color doppler scan, and were correlated clinically and hormonally. Results: The ovarian artery mean pulsatility index (PI) was observed to be 4.05 in control group and 2.58 among PCOS cases, which is signicantly decreased in cases. Comparing non-obese and obese PCOS cases, the mean ovarian artery PI was found to be 2.65 and 2.51 respectively. The difference was not signicant. In our study, the resistive index (RI) of ovarian artery also showed a signicant decrease among PCOS cases with mean value of 0.62, compared to 0.9 in the control group. The PI and RI of uterine artery in both obese and non-obese cases were signicantly increased in comparison to control group. Transvaginal colour doppler helps in adequate evaluation of haemodynami Conclusion: c changes in small vessels of utero-ovarian circulation. It can aid in diagnosis as well as serve as prognostic indicator in patients suffering from PCOS.

Background: The high mortality associated with ovarian cancer is due to delayed detection. Novel agents are being developed for more targeted therapy. Hence, a more accurate interpretation of the lesion is required. DW-MRI forms a promising tool in the same. Aims & Objectives: To assess the diagnostic potential of DW-MRI in the evaluation of ovarian mass lesions. Methods: 103 women with ovarian lesions were evaluated with DW-MRI. The characteristics were recorded, analysed and compared with histopathology reports wherever possible. Results: With a sensitivity of 93.94%, a specicity of 98.08% and accuracy of 96.47%, DW-MRI is a promising tool to be considered in the evaluation protocol of ovarian mass lesions, for a more accurate interpretation. Conclusion: With advancements like diffusion-weighted, in conventional MRI, the diagnostic performance has been improved and needs to be utilised in the evaluation of ovarian mass lesions
