High-frequency sound waves are emitted by an instrument called a ‘transducer’ placed on the animal’s body. These waves are reflected as echoes from the structures within the body and are picked up by the transducer. A computer converts the echoes into visual patterns, revealing the scale & size, organ structure, and development of organs. The pictures are displayed on a monitor during the examination. They are captured electronically as instant images or recorded on videotape or media storage, counting on the machine’s capability.
There is little-to-zero discomfort for your animal during ultrasound examinations, although areas of hair must be clipped and shaved, especially the abdominal area. Coupling jelly is applied between the transducer and your pet’s skin for better viewing. Sedation or general anesthesia could also be required in some cases to keep the patient still for a close examination.
