Veterinary B-ultrasound diagnostic elements for in vivo examination of ewe

Edit: Henan Tianchi Instrument Equipment Co., Ltd    Date:2020-06-17
Veterinary B-ultrasounds generally use the bladder as the positioning marker during the in vivo examination of the ewe. However, when the urinary wave of the bladder is low, the positioning is difficult. Sometimes a small amount of urine in the bladder is mistaken for the gestational sac. However, the bladder is used for veterinary ultrasound until the bladder can be seen on the monitor. The bladder is used as a reference point. The position of the uterine horn is slightly forward, moving back and forth and rotating clockwise or counterclockwise to obtain a complete image of the reproductive tract. The correct reading of veterinary B-ultrasound images and the reading of sound images, in addition to the judgment while operating, generally requires a consultation with a person with experience in reading images to avoid false negatives. After 60 days of pregnancy, the fetus is located in the lower abdomen due to the weight of the fetus. Therefore, it is necessary to push the abdomen up in front of the hind legs so that the uterus of the ewe enters the effective range of the veterinary B-ultrasound probe.
The gestation of pregnant ewes reaches 80 days (12 weeks), and the sound image of the complete fetus can be seen. For early diagnosis using veterinary ultrasound, an echogram of the ovary is also needed to aid diagnosis. The ovary is slightly enlarged and the circular low echo area is visible in it, which is the corpus luteum (normal ovaries generally show homogeneous low and medium echo, and the follicles are small). There is no echo in the round shape, and the medulla is located in the middle, showing irregular and slightly strong echo).
When veterinary ultrasound is used to detect ewes, the fecal ball in the rectum of the ewes can bring about the influence of sound and shadow, but it can be excluded from the operation inspection of the ewes by veterinary ultrasound. Abdominal inflammation, uterine malformation, endometritis, uterine adenoma, fibroids, etc. caused by surgery may be misjudged as pregnancy in different periods or affect the diagnosis.
