A computed tomography (CT) scan is a diagnostic test in which multiple x-rays of an area are taken and a computer generates a 3D view. Today, our Tigard vets explain CT scans, when and why they are necessary, and the average cost of a CT scan for dogs.
How do CT scans work?
A CT scan generates image slices of the area that is being evaluated. Imagine these areas were a loaf of bread. The CT scan produces pieces that can be lifted out, examined from all angles, and replaced. It provides far more information than a standard x-ray.
When your dog needs a CT scan, it will be sedated with anesthesia. The sedation is used to keep your pet calm and still during the procedure, as any movement will degrade the image quality. A trained technician administers it under the supervision of a veterinarian.
Your pet will be moved into the scanner after being sedated. It looks like a large white donut. The scanner's X-rays begin spinning, capturing images that will be used to build an internal picture. Intravenously, a contrast dye can be used to highlight soft tissues and blood vessels.
When are CT scans necessary for dogs?
There are many situations in which a regular X-ray or ultrasound scan cannot provide the visual detail that is available through the use of CT scanning. CT scans are particularly useful in detecting issues, such as:
- Nasal disease
- Head trauma
- Lung diseases
- Middle and inner ear disorders
- Tumors
- Orthopedic conditions, such as hip dysplasia and joint degeneration
- Brain or spinal conditions
- Dental diseases, such as abscesses
CT scans are frequently performed on dogs with cancer diagnoses to determine whether and how far the cancer has spread.
Are there side effects of CT scans for dogs?
No, there shouldn't be. While humans who have multiple CT scans throughout their lives may be at an increased risk of radiation-induced cancers, repeat scans for dog and cat patients are uncommon. A dog's lifespan isn't long enough for this to be a concern.
However, as with any anaesthetic procedure, the patient should be monitored for a short period of time for any adverse effects.
What is the price of CT scans for dogs?
The cost of a CT scan for pets is determined by the scan's complexity and the scope of the study. Scans that require iodine injection, for example, may cost significantly more than those that do not. Costs may also vary depending on the veterinarian and geographic location. The total cost in New York City can be very different from the total cost here in Tigard.
