Diagnostic Imaging: X-rays and CT Scans For Cats and Dogs

Diagnostic Imaging: X-rays and CT Scans For Cats and Dogs

Whether during routine visits or if needed for a specific concern, technology can be of great assistance. Our Crystal Lake vets talk about why diagnostic imaging is helpful in pet care and why your dog or cat may need X-rays or CT scans.

Routine Diagnostic Imaging for Dogs or Cats

Diagnostic imaging tools such as X-rays, ultrasounds and CT scans are used to help the vet gain valuable insight into the internal functions and state of your pet's health.

Electromagnetic radiation and other technologies are used in routine diagnostic imaging procedures for dogs and cats. They capture extremely detailed images of your pet's bones, soft tissues and other internal structures so your vet can offer an accurate diagnosis and plan effective treatments. 

What to Expect With X-rays and CAT Scans of Cats and Dogs

While both are used to gain a better view of the internal functions of dogs and cats, X-rays and CT scans are performed differently:

X-rays (Digital X-rays or Radiography)

With a digital X-ray (radiograph) for cats or dogs, we use very low doses of radiation to examine the inside of the body to reveal important information that might not be easily viewed from the outside.

This procedure is used to evaluate organs and bones and to diagnose conditions such as spinal cord diseases, arthritis, broken bones, bladder stones and some tumors.

You can also rest easy knowing that X-rays are safe for dogs and cats of all ages and in all conditions. The level of radiation is so low that it can even be used on pets that are pregnant.

CT Scans (CAT scans)

Often referred to as a CAT scan or CT scan, computed tomography is useful when assessing the nasal passage, sinuses, lungs, thorax, ears, abdomen and some orthopedic areas.

Your vet might recommend a CT scan if your pet has any condition ranging from lung disease to pulmonary fibrosis, metastatic cancer (before surgery), tumors or masses in the chest cavity, disease in the nasal cavity, trauma to the spine or pelvis, vascular anomalies or orthopedic developmental disease (elbow dysplasia).

When CT scans are used to for diagnosing imaging, your vet can gain a more distinguished view of the bones and soft tissues. For the scan itself, your pet will be placed on a table that will slowly enter the machine and a full image will be produced. These scans can be performed quite quickly.

For these types of scans, an X-ray tube rotates around the patient to record images from several angles (the suspected health issue will determine the number of images captured) to create slices. The slices are then stacked together to produce a 3D image of your pet without superimposition of other tissues or organs.

Will your dog or cat need to be sedated for diagnostic imaging?

When a pet is having an X-ray, whether or not they are sedated depends on their temperament, whether they can sit still and if the X-ray itself can be performed while your dog or cat is in a comfortable position. The vet may still recommend using anesthesia when taking images of certain parts of your pet's skeleton.

When having a CT scan, your dog or cat will need to lie absolutely still for the entire duration. Because your pet will be heavily sedated, they will have their vitals monitored the entire time.

If biopsies need to be done before an ultrasound, your pet will require a heavy sedative or short-acting anesthetic to help them relax while the vet performs the procedure and to avoid potential complications. Your vet will notify you if this is required.

What can I expect after my pet's diagnostic imaging appointment?

Our veterinarians will review results from digital X-rays and ultrasounds in-house and will come up with a treatment plan suited to your pet's needs and conditions.
