Endocrine abnormalities in ovulatory women with polycystic ovaries on ultrasound.
Polycystic-appearing ovaries (PAO) on ultrasound have been described in a variety of endocrinopathies and also occur in ovulatory women. By some investigators this is merely referred to as 'PCO' (polycystic ovaries). Although there is controversy in this regard, we do not consider women with PAO/PCO who have no known endocrine disturbance to have polycystic ovary syndrome (PCOS) and therefore p...
متن کاملModelling artificial ultrasound images of ovaries
A new algorithm for creating artificial images (phantoms) of ovaries is presented. The entire process of a phantom formation is divided into two parts. First, an ovary with ovarian follicles is modelled. The ovary is approximated with a cube, while the follicles are assumed ellipsoids with excrescences on their surface. Afterwards a model of the ultrasound scanning process is set. The probe is ...
متن کاملAbsorption of ultrasound by mammalian ovaries.
The transient thermoelectric method was employed to determine the ultrasonic absorption coefficient of excised bovine, canine, feline, murine, ovine, and porcine ovaries at 1 MHz. The dynamics of the organ yields significant variations with physiological stage and structure. Values ranged from 0.017 cm-1 for the follicle to 0.050 cm-1 for the corpus luteum, largely reflecting macromolecular con...
متن کاملNormal Renal Dimensions in Iranian Adults Measured by Ultrasound
Introduction: Correct interpretation of kidney images requires the knowledge of its normal size. This study aimed to establish normal values for kidney length and parenchymal thickness and identify the potential related factors in a group of Iranian adults. Methods: Renal dimensions, including length and parenchymal thickness were measured by sonography in 103 individuals with n...
