Analysis of Follicle Wall of Normal and Polycystic Ovaries
Objectives: It is important to recognize and diagnose various forms of ovulatory failure that contribute to infertility. Polycystic Ovary Syndrome (PCOS) is one such failure characterized by the formation of numerous follicles in the ovary. This disorder seriously affects women's health and it is diagnosed by ultrasound imaging which gives important information on the number of follicles and their size.
Materials & Methods: These follicles are fluid filled structures that exhibit echo texture. Texture features of the follicle wall for both normal and PCOS dominant follicles are evaluated over a period of seven days before ovulation.
Results: By considering these features, follicle growth rate is investigated in normal and PCOS.
Conclusion: The results supported the hypothesis that quantitative changes in echo texture are reflecting the changes in the physiologic status of the normal ovary.
