First the ultrasound is best performed when the pet is fasted to avoid gas in the intestines distroting the images.
The tummy fur must be clipped so that the ultrasound probe can pass smoothly over the belly. Special ultrasound gel is massaged over the tummy.
Images are taken with precision and saved as the examination continues for about 20 minutes. Depending on the area examined, the pet may have to be positioned differently to acquire the pictures and video.
The gel is then wiped off the tummy and the Doctor reviews the images, or sends the pictures and videos to a radiologist for a second opinion.
