Transrectal real-time ultrasound scanning of the cow reproductive tract

A transrectal real-time ultrasound scanning of the cow reproductive tract allows the operator to view images of structures which normally can be only palpated. The device used in these studies allowed exact evaluation of the cow reproductive tract for position, size and consistency of ovaries, uterus and fetuses; these parameters cannot be described to this level of exactness even by the most skilled palpators. This paper describes real-time ultrasound scanning of an ovary containing a cystic corpus luteum and several follicles and ofa nonpregnant and a pregnant tract at different stages of gestation. The device may be expected to aid both the researcher and the practicing veterinarian considerably in the future.
