An ultrasound test is a painless and non-invasive medical procedure used to view structures within the body. It is routinely performed in veterinary practices to help diagnose a range of conditions in pets.
How Does Ultrasound Work?
An ultrasound machine emits and receives high-frequency ultrasound waves that are inaudible to humans. These sound waves are absorbed or reflected, depending on the density of the structures within the body. Reflected ultrasound waves are measured by the machine and translated into an image of a pet’s tissues.
Is Ultrasound Safe and Effective?
Ultrasound tests do not use radiation and there is no evidence that they are harmful to pets. They are effective for examining soft tissues and organs, but cannot be used to examine the lungs as ultrasound waves do not pass through air.
Which Conditions Can Ultrasound Help Diagnose?
Ultrasound tests are useful for diagnosing conditions which affect the organs or other internal structures. These include liver and kidney disease, bladder conditions, tumors, and heart conditions. Ultrasound tests are also used to diagnose pregnancy in female animals.
How Is an Ultrasound Test Performed?
Prior to an ultrasound test, you will need to withhold food from your pet for a period of at least 12 hours. Water is permitted, and it is preferable that your pet’s bladder is full if they will undergo an abdominal ultrasound.
Most pets will not require anesthesia since an ultrasound test is painless and non-invasive. However, some pets may need to be sedated if they are anxious or in a lot of pain. Sedation will also be required if tissue biopsies need to be collected.
In most cases, your veterinarian will shave your pet’s fur in the area where the ultrasound test will be performed. A gel will then be applied to the skin to improve the transmission of ultrasound waves.
During the test, a probe will be pressed against your pet’s skin to obtain the necessary images. Following the procedure, results will be evaluated and compiled into a final report. This may be done at the clinic or by an outside veterinary specialist. Your veterinarian will then discuss the results of the report with you. In some cases, there may be a short wait to learn the results of your pet’s ultrasound. For more information please consult with your veterinarian.
