The Radiology Department provides advanced diagnostic imaging as well as consultation with your veterinarian for the best mode of imaging for your pet. Our highly trained specialists are dedicated to providing the best care in order to accurately identify and diagnose disease. Diagnostic imaging, such as radiographs and ultrasound, are commonly part of a diagnostic work-up if your pet is having a problem or as part of a general wellness examination in an older pet to detect potential problems early. More advanced diagnostics, such as an MRI or CT may also be suggested by your veterinarian or one of our specialists depending on each situation.

We are in constant contact with your regular veterinarian updating our findings, or consult with them about the best next step in regards to imaging modality. Our in-house radiologist is always happy to answer any questions that you or your veterinarian may have regarding imaging. If you have questions, please give us a call.
