Positron Emission Tomography, commonly known as PET imaging, is an advanced diagnostic tool used in both human and veterinary medicine. If you’re a pet owner wondering, “Can You Do Pet” PET scans, the answer is yes, in certain specialized veterinary centers. This article will explore what PET scans are, how they work for pets, and what you need to know if your veterinarian recommends this procedure for your animal companion.
What is a PET Scan and How Does it Work for Pets?
A PET scan is a type of imaging test that allows veterinarians to visualize the biological function of your pet’s body, rather than just the anatomical structure as with X-rays or CT scans. It works by detecting radiation emitted from a radioactive substance, called a radiotracer, which is administered to your pet. This radiotracer is often attached to molecules like glucose, which the body uses for energy. Because diseases like cancer often have increased metabolic activity, they show up more brightly on PET scans.
The Science Behind PET Scans for Animals
The radiotracer emits tiny particles called positrons. When these positrons collide with electrons in the body, they annihilate each other and produce gamma rays. These gamma rays are detected by the PET scanner, which then creates detailed 3D images showing where the radiotracer has accumulated in your pet’s body. Areas with higher metabolic activity, such as tumors or sites of inflammation, will concentrate more of the radiotracer and appear brighter on the scan.
Why Are PET Scans Used in Veterinary Medicine?
While not as widely available as other imaging techniques, PET scans offer unique advantages in veterinary diagnostics. They are particularly useful for:
- Cancer Detection and Staging: PET scans can help detect tumors, determine if cancer has spread (metastasized), and assess the effectiveness of cancer treatments.
- Neurological Disorders: PET imaging can be used to study brain function and identify abnormalities in pets with neurological conditions.
- Cardiac Disease: In some cases, PET scans can help evaluate heart function and identify areas of damage or disease.
- Research: PET scans play a crucial role in veterinary research, helping to advance our understanding of animal diseases and develop new treatments.
Preparing Your Pet for a PET Scan: What to Expect
If your veterinarian recommends a PET scan for your pet, it’s important to understand the preparation process to ensure the safety and success of the procedure.
Pre-Exam Instructions: Ensuring Your Pet’s Safety
Just like with human PET scans, there are specific guidelines to follow before your pet’s appointment:
- Allergies and Medications: Inform the veterinary team about any allergies your pet has or any adverse reactions to medications they have experienced in the past. Provide a complete list of your pet’s current medications.
- Pregnancy: If your pet is female and there’s any possibility she might be pregnant, inform your veterinarian immediately as radiation exposure can be harmful to a developing fetus.
- Valuables: It’s best to leave valuable items at home to avoid any risk of loss or damage during the procedure.
- Interpreting Services: If you require language interpreting services, let the veterinary clinic know in advance so arrangements can be made.
- Dietary Restrictions: Typically, your pet will need to follow a limited carbohydrate diet for 24 hours before the PET scan. This helps to optimize the uptake of the radiotracer.
- Fasting: Your pet will usually need to fast for 6 hours before the exam, meaning no food. Water is generally allowed up until arrival and encouraging your pet to drink water is helpful for hydration and the procedure.
- Routine Medications: Unless instructed otherwise by your veterinarian, your pet can usually take their routine medications. If your pet is diabetic and on insulin, discuss the timing of medication with your vet, typically it may be administered no less than 4 hours prior to the exam.
- Arrival Time: Arrive 15 to 30 minutes before your scheduled PET scan appointment to allow time for check-in and preparation.
- Contrast and IV Line: In some cases, a contrast agent may be used to enhance the images. If the veterinary radiologist determines contrast is needed, a small intravenous (IV) line will be placed in your pet’s vein to administer both the contrast and the radiotracer.

What Happens During the PET Scan?
The PET scan procedure itself is generally painless for your pet. Here’s what you can expect:
- Verification and Forms: The veterinary technologist will verify your pet’s identification and the exam being requested. You may be asked to complete a contrast screening form.
- Positioning: The technologist will carefully position your pet on the exam table to ensure optimal image quality.
- Stay Still: It’s crucial that your pet remains as still as possible during the scan to prevent blurry images. The technologist will provide instructions and may use gentle restraints or sedation if necessary to help your pet stay still. You will likely not be able to stay in the room during the scan to minimize your own radiation exposure.
- Duration: The duration of the PET scan can vary, but it typically lasts around 2 hours.
- Questions: You will have the opportunity to ask the technologists questions before and after the procedure.
After the PET Scan: Pet Aftercare and What to Watch For
Following the PET scan, there are a few important aftercare instructions to ensure your pet’s well-being:
Post-Procedure Care for Your Pet
- Hydration: Encourage your pet to drink about 5 glasses of water (or an appropriate amount for their size) over the next few hours to help flush the radiotracer and contrast agent (if used) out of their system.
- Nursing Mothers: If your pet is a nursing mother, it’s recommended to wait 24 hours before resuming breastfeeding to minimize any potential radiation exposure to the offspring.
- Monitoring for Symptoms: While reactions are rare, it’s important to monitor your pet for any unusual symptoms after the PET scan.

When to Seek Veterinary Attention Post-Scan
Contact your veterinarian immediately or seek emergency veterinary care if you observe any of the following symptoms in your pet after the PET scan:
- Nasal congestion
- Itchy eyes
- Hives or rashes
- Sneezing
- Restlessness or tremors
- Pain
- Nausea or vomiting
- Dizziness
The veterinary staff is trained to handle any potential reactions, but it’s crucial to be vigilant even after you leave the clinic.
Conclusion: PET Scans as a Valuable Tool for Pet Health
PET scans are a sophisticated and valuable diagnostic tool that can significantly enhance the care of your beloved pets. While the question “can you do pet” PET scans is answered with a yes, it’s essential to remember that this procedure is typically performed at specialized veterinary centers. If your veterinarian believes a PET scan could benefit your pet, discuss the procedure in detail, understand the preparation and aftercare, and ensure you choose a qualified veterinary facility to perform the imaging. This advanced technology can provide critical insights into your pet’s health, leading to more accurate diagnoses and effective treatment plans.
