About CT Scans and X-rays on Cats and Dogs
Computed tomographic imaging, also known as a "CT" or "cat scan", works by producing multiple individual images or "slices" throughout a region of interest in the body through the use of radiation (X-rays) and a computer. A common comparison to an image produced by a CT scanner is individual slices of bread that make up a complete loaf. The CT machine produces two-dimensional slices of a section of your pet’s anatomy and then configures them into a complete image we can view. These slices can also be used to create three-dimensional reconstructions that can be very useful for things like surgical planning. Once the images are produced, they are sent to a veterinary specialist to review and interpret.
An X-ray is a quick, painless test that produces images of the structures inside your cat and/or dog's body, mainly their bones. X-ray rays pass through the body, and are absorbed in different volumes depending on the density of the material that they have to pass through.
What can a dog or cat X-rays and CT scans help vets diagnose?
X-rays are one of the most helpful, and frequently used tools in both human healthcare and veterinary healthcare. X-rays can help vets to get a view of your pet's bones, tissues, and internal organs so that they can diagnose issues such as broken bones, bladder stones, swallowing foreign objects, and more.
X-ray images can help vets to spot some tumors and enlarged organs which may lead to a diagnosis such as heart disease or cancer. An X-ray of a pregnant pet can also help you to prepare for labour by allowing you to know how many babies you are expecting, and whether a c-section may be required for any reason.
A detailed view of organs, tissues, and ligaments cannot be obtained using x-ray technology. In these cases, other diagnostic imaging such as MRI and Ultrasound are more beneficial.
The high-resolution images produced by the CT machine help us to evaluate your pet's anatomy in great detail - a detail that we would otherwise not be able to see using standard X-rays. CT scanners provide excellent detail of bony and soft tissue structures in the body.
How can I prepare for my dog or cat's X-ray or CT scan appointment?
Often X-ray and CT scans are done when a pet is brought in to have a particular issue looked at by the vet.
For that reason, no preparation is required. Your vet will examine your pet, then if an X-ray or CT is required, they will take some time to explain the procedure and what they will be looking for.
If you have an X-ray or CT scan that was booked ahead of time for your pet, your vet will provide all instructions you will need for the day of the procedure.
Will my dog or cat be sedated when they have their X-ray or CT scan?
Sedation is sometimes required to get a clear X-ray.
If your dog or cat is calm, not in too much pain, and able to lay in a comfortable position while the X-ray is being taken, sedation will not be necessary. On the other hand, if your dog or cat is squirmy, edgy, or in pain sedation will be recommended.
Other reasons why sedation may be used during an x-ray include if the pet's muscles need to be relaxed to get a clear image, or when the X-ray is being used on the skull, teeth, or spine.
CT scans usually take longer than X-rays, and your pet needs to be completely still for one. As a result, general anesthesia is usually recommended ahead of CT scans.
Are X-rays and CT scans safe for dogs and cats?
While the use of X-rays and CT scans are generally considered safe for dogs and cats, radiation is involved, so X-rays and CTs are typically used only occasionally and generally as a diagnostic tool.
If you're concerned about the use of X-ray or CT scanner technology and your pet's health, speak to your vet. Your veterinarian will be able to give you an understanding of the risks versus the benefits in your dog's and cat's particular case so that you can decide whether you want your dog or cat to have an X-ray or CT scan.
How much will my dog or cat's X-rays or CT scan cost?
There is a range of factors that will dictate the cost of your dog or cat's X-rays, ranging from the size of your pet, the area being X-rayed, whether sedation was used, the type of clinic, where your veterinary clinic is located, and more. If you are concerned about the cost of your cat or dog's X-rays, ask your vet for an estimate before proceeding.
CT scans are the same as X-rays, the cost will be different based on what needs to be done to your pet. The entire process of a pet CT scan takes about 45 minutes to an hour, not including anesthesia, so the price can change.
Diagnostic Imagining at Westfield Animal Hospital
While our vets in Westfield do not offer CT scans, we can offer digital X-rays to examine your pet's internal systems to uncover information that could be invisible to us from the outside. We can also use digital dental X-rays to see below the gumline where damage from periodontal disease hides.
We can also provide Ultrasounds, ECG/EKG, Fecal Exams, Urinalysis, and Bloodwork.
