“Ultrasonic sound waves create images of internal body structures based on the pattern of echos reflected off tissues and organs. A useful tool in the diagnosis and management of several medical issues affecting exotic companion animals.”

Comprehensive Veterinary Ultrasound.

Ultrasound2Ultrasonography is a safe and relatively non-invasive tool that allows the visualization of structures not otherwise visible. It has become an essential and uniquely useful diagnostic tool for the veterinary community. Its applications on animals are as diverse as they are in human medicine. It is the second most useful imaging resource in veterinary practice. Depending on particular patients, stress levels and importance of an adequate image, some procedures may require light sedation.

In contrast to radiography, which uses radiation, ultrasonography uses sound waves to penetrate internal organs and structures. The result is a reflected image of the various structures. The reflected sound waves are created into a computerized image and projected onto a monitor which can then be interpreted by a trained veterinary or veterinary ultrasonographer. Tissues and fluids reflect sound the best, while gas/air and bone prevent the transmission of the sound waves.

So Why Do You Shave the Fur or Remove/Soak Feathers?

Fur/hair  and feathers trap air. Since air inhibits the transmission/reflections of sound waves, the patient must be shaved or sprayed down with alcohol. Gel is then applied to the area to further block out air between the patient and the tip of the hand-held probe.




Coelomic Fluid – Avian/Duck

This duck presented to SEAVS with difficulty breathing.  Upon physical exam it was suspected that the animal had free fluid in its coelom (the equivalent of an abdomen in a mammal).  Doctors used ultrasonography to confirm their diagnosis and proceeded to aspirate large amounts of serosanguinous fluid.
