Patient Stories

WSU veterinary student, Beryl Swanson ('14 DVM) with Mr. Bear after surgery.

Mr. Bear is one of thousands of patients who has been helped because of MRI

After noticing an odd lump on his dog's head in the spring of 2013, Joel Greenhalgh of British Columbia, Canada he took Mr. Bear, a then 11-year-old Australian Shepherd-Rottweiler mix, to his local veterinarian. At first the advice was to watch and see, but when it didn't go away, his veterinarian took a biopsy. Mr. Bear had cancer.

The Canadian oncologist referred, Mr. Bear to WSU. Neurologist Dr. Annie Chen and veterinary student Beryl Swanson at the WSU Veterinary Teaching Hospital, examined Mr. Bear and got him in right away for an MRI.

"MRI is the best way for us to evaluate the brain," said Dr. Chen.

MRI scan of Mr. Bear's tumor

Originally, Mr. Bear's local veterinarians had believed he just had a lump on the outside of the skull, but the MRI results showed that the cancerous skull tumor was also growing into the skull and pressing on the brain. Dr. Chen and her team took MRI scans from different angles and used different techniques to see the exact location of the tumor and where the blood vessels were.

"We needed to know how far the tumor had extended," said Dr. Chen. "To know up to the millimeter is very important."

By knowing where the edges of the tumor were, Dr. Chen could better explain the benefits and risks of the surgery. She also saw the tumor was growing very close to a major blood vessel, which added to the risk. But, the MRI made all the difference.

"By having the images, we felt confident we could approach that area and do the surgery," said Dr. Chen.

After long and very delicate surgery, the tumor came out cleanly and they removed more than 90%. Because Dr. Chen knew where the vessel was from the MRI scan, she was able to tease the tumor away from the vessel and not tear it. WSU oncologists followed up with radiation to kill the remaining cancer cells.

"WSU saved my dog's life," said Joel Greenhalgh.
