You've just found out that your dog or cat needs an ultrasound. So, what exactly is an ultrasound and how can it help your pet? Our Edgewater vets explain how ultrasound scans are performed and what they are used for.
Our pets frequently get into things they shouldn't or develop health problems like cysts or tumors that necessitate treatment. Ultrasounds are a type of imaging technology that uses sound waves to create a 'picture' of a specific part of your pet's body.
Veterinary ultrasounds are non-invasive and can be used to diagnose or evaluate problems with your pet's internal organs or check on your pet's pregnancy.
Reasons Your Pet May Need An Ultrasound
An ultrasound can help internal medicine vets examine the structure of your pet’s organs so they can discover and identify blockages, tumors, or other problems.
Ultrasounds are done in an in-house veterinary diagnostic laboratory. Veterinarians use ultrasounds and other diagnostic tools to provide an accurate diagnosis of your pet’s medical issues, so they can provide your pet with the most effective treatment possible.
Through the use of ultrasound, they are able to distinguish soft tissue masses from foreign bodies or fluid - a task they might find challenging or impossible to accomplish with a digital X-ray. The sound waves the ultrasound generates are not harmful or painful to your cat or dog.
Conditions That May Require An Ultrasound
If your cat or dog has a heart condition, your primary care veterinarian may refer you to our specialists for a heart ultrasound or echocardiogram to assess the overall health of your animal's heart and look for abnormalities.
Abnormal Blood or Urine Test Results
If your veterinarian discovers abnormalities in your pet's blood or urine tests, he or she may recommend an abdominal ultrasound to get a clear picture of the health of your pet's internal organs, such as the lymph nodes, spleen, kidneys, liver, urinary bladder, or other areas to determine why the abnormalities are occurring.
Examination of Soft Tissues
Almost all soft tissues can be examined thanks to ultrasound technology. A few of the most common areas that ultrasounds are used on include:
- Fetal Viability and development
- Thyroid glands
If abnormal tissue is spotted during an ultrasound, the vet may also use the ultrasound to help collect tissue samples from the affected area.
Ultrasound-Assisted Tissue Collection
Samples are typically collected using these methods:
- Tru-Cut biopsies
- Ultrasound-guided fine needle aspiration
If your vet will be performing an ultrasound-assisted tissue collection, your pet will likely be sedated. they can perform biopsies in a less invasive manner with ultrasounds than with surgeries.
Types of Ultrasounds
Your vet may perform these two types of ultrasounds:
If your pet is in distress, the ultrasound will usually concentrate on the abdomen and chest to determine whether your dog or cat has a serious internal hemorrhage (bleeding) or pneumothorax (a condition in which gas or air collects in the space surrounding the lungs).
This can assist us in diagnosing the issue quickly. they can then plan effective treatment.
Also referred to as cardiac ultrasounds, these detailed ultrasounds they can closely assess the heart and its surrounding structures, including the pericardial sac. This will tell us whether the heart is functioning properly and whether there is a malfunction in the heart.
Though they are usually painless, echocardiograms require several measurements and calculations. If your pet was recently diagnosed with a heart murmur or is displaying signs of heart disease, they may be referred to our specialists for an echocardiogram.
Once an abnormal part of an organ is identified, an ultrasound-guided biopsy can be performed to collect a sample of the affected tissue. This biopsy allows us to obtain a tissue sample, which can then be examined under a microscope to reveal additional information. This will almost always result in a diagnosis.
How To Prepare Your Pet for an Ultrasound
Ultrasounds in different areas require different preparations. Speak to your vet to find out how to prepare your pet for its ultrasound.
For abdominal ultrasounds, you may be asked to refrain from eating or drinking for 8 to 12 hours. They can examine the urinary bladder most thoroughly when it is full of urine. This is why, if possible, your cat or dog should not urinate for 3 to 6 hours before the ultrasound.
The area to be examined will likely be shaved so clear images can be produced. While most pets will remain still and cooperative during the ultrasound, some will need to be sedated.
If biopsies need to be done, your pet will need a heavy sedative or short-acting anesthetic to help them relax during the procedure and prevent potential complications that could impede success. Your veterinarian will let you know if this is necessary.
Getting Your Pet's Ultrasound Results
Our veterinarians can see results almost immediately because they can perform an ultrasound in real-time. After being captured, ultrasound images are sometimes sent to a veterinary radiologist for further consultation. You may have to wait a few days for the final result in these cases.
