Yes, pet CT scans (Positron Emission Tomography-Computed Tomography) are generally safe for pets when performed by a qualified veterinarian or veterinary specialist. These scans combine CT imaging (which provides detailed images of internal structures) with PET (which shows the metabolic activity of tissues) to help diagnose a variety of conditions, including cancer, infections, and other serious health issues.
However, like any medical procedure, there are a few considerations to keep in mind regarding the safety of a PET CT scan for pets:
---
1. Anesthesia or Sedation
Anesthesia: In most cases, pets require sedation or anesthesia to stay still during the scan, as movement can affect the image quality. While anesthesia is generally safe, there are some risks, particularly for older or compromised pets. A veterinarian will assess your pet's health beforehand to minimize any potential risks.
Monitoring: During the procedure, the pet will be closely monitored by veterinary professionals to ensure that the sedation or anesthesia is safe.
---
2. Radiation Exposure
Radiation Levels: Both PET and CT scans involve exposure to radiation, but the amount is relatively low and considered safe for pets. Your veterinarian will carefully evaluate whether the benefits of the scan outweigh any potential risks of radiation exposure.
Safety Protocols: Veterinary clinics and hospitals follow strict protocols to minimize exposure to radiation. Only the necessary areas will be scanned, and radiation protection is used to shield areas not being imaged.

3. Age and Health of the Pet
Age Considerations: Older pets or pets with pre-existing health conditions may have a higher risk when undergoing sedation or anesthesia. Your veterinarian will take these factors into account and may recommend alternative imaging methods if necessary.
Health Assessment: Before performing the scan, the vet will conduct a thorough examination of your pet's overall health to ensure they're fit for the procedure.

4. Purpose of the Scan
Diagnostic Benefits: PET CT scans provide valuable information that can help diagnose complex conditions, particularly cancers or neurological disorders. The scan can reveal the exact location of abnormal tissue or tumors, which aids in treatment planning.
Non-Invasive: The procedure is non-invasive (no surgery involved), which makes it a safer option compared to other diagnostic methods, such as biopsy or surgery.

5. Alternatives to PET CT
X-rays, Ultrasound, and MRI: Depending on your pet's condition, your vet might recommend other imaging options that carry less risk or may be more appropriate for the situation.

Conclusion
PET CT scans are safe for most pets, especially when performed by experienced professionals and when the procedure is deemed necessary for diagnosis and treatment planning. As with any medical procedure, it's important to discuss any concerns with your veterinarian beforehand, particularly if your pet has any health conditions that could affect their response to anesthesia or radiation.
