1...Obtain the best image possible. 
Take the time to completely evacuate the rectum, and use plenty of lube for contact. If your ultrasound system provides variable frequency transducers, remember to operate at the highest frequency that still allows you enough depth to visualize all the pertinent structures; this will optimize the resolution of your image! You’ll acquire a higher quality (and larger!) ovary image scanning at 6cm than you will at 12cm. In addition, become familiar with your equipment; experiment with gain, contrast, and persistence in order to achieve the image that you desire.

Dr. Michelle Oakley, Yukon Vet, uses the IBEX^® EVO^® in the clinic, too. She is using the C6E probe [multi-frequency transducer, 4-9 MHz, 18 cm depth] to diagnose Barney, her canine patient.

Dr. Michelle Oakley, Yukon Vet, uses an IBEX^® EVO^® in the wild. She is using the L6E probe [linear transducer, 5-8 MHz, 18 cm depth] and wearing our latest high-resolution i3 goggles.

Mummification in bovine fetuses has an incidence of less than 2%. It occurs when there is fetal death for any number of reasons (Trichomoniasis and BVD infections have been specifically implicated as causes), but the CL is retained, the cervix stays closed, and there is no bacteria or oxygen present in the uterus to cause maceration. 

If you’re new to ultrasound, an image may look like nothing more than a swirling array of grey tones on the screen.  Interpretation requires an understanding of anatomy and physiology, but also of how ultrasound technology functions.

Consider the sonar produced by a bat in flight. The bat emits high frequency sounds, which then bounce off of objects in its proximity and return to the bat. The animal uses the strength, direction, and timing of the returning sound to determine where those objects are and to avoid a collision.
