Ultrasound allows the doctor to examine the internal organs of your pet in a painless manner with no known side effects. It is more sensitive than Xrays for seeing "inside the body".
It can be used to uncover structural damage, deformities, or abnormalities to the heart, liver, stomach, kidneys, and other major bodily organs. Ultrasound can also capture "real time" movements of the organs, so functional abnormalities can also be found.
During an ultrasound, high frequency sound waves are pulsed into your pet’s body. They do not feel this and it does not cause any discomfort. Many people relate ultrasounds to pregnancy exams to show the baby inside the mother, but it has many other uses.
Ultrasound technology can help to catch diseases and other health problems at early stages. This is important in helping your pet fight any diseases they may be afflicted with before the problem becomes serious.
