Ultrasonography

Ultrasonography is a technique that offers diagnostic images by using ultrasounds that are produced by specific probes.

When ultrasounds pass through a tissue they are reflected by tissue boundaries and are received back by the probe. Based on sound speed in tissues, the computer can calculate the distance between the reflection boundaries and the probe. In this way an image with different shades of grey is created. In addition, the Doppler technique, combined with standard ultrasonography, allows studies of blood flow.

Ultrasonography is a diagnostic procedure that is performed in real time. Every movement of the pet or probe immediately modifies the image. Because of this characteristic, ultrasonography is also used for the evaluation of heart and other structures in motion. Ultrasonography is usually an anaesthesia-free procedure, unless the pet is unable to stay in slightly forced positions. A complete exam usually lasts about 30 minutes.
