Abstract:

The aim of the present study was to explore the ultrasound image features of pregnant bitches of the reproductive system at different times.In our study,8 standard test Beagles are selected,and the color Doppler instrument was used.The uterus,ovaries and fetus were observed by real-time tracking and monitoring under the two-dimensional gray-scale and color Doppler ultrasound mode.The ultrasound images we got were summarized and analyzed,meanwhile the bitches testing by vaginal smear microscopy.The result of ultrasound image showed that the ovaries and uterus’s volume increased significantly,the line was clear,the follicle was obviously,and the womb milk like ‘thin’ in uterine cavity was visible during the heat period.We tested the fetus at the 23 d of gestation by ultrasound.The blood stream of ovaries was obviously and plentiful,the arteriovenous fistula of ovary from the back cavity vein and the abdominal aorta twisted together as red and blue strap interlace,and flow into the ovary during the estrus by color Doppler ultrasound machine;the blood of uterine was more plentiful gradually after pregnancy,internal diameter and signal intensity of blood vessel rising quickly.The size,blood stream distribution can change during physiology period,and real-time monitored regular pattern of ultrasound image of the ovary,uterus and embryo by ultrasound will provide reference information for bitches reproductive system development and clinical examination.
