Kim, we had an MRI done on Butkus, and yes, it was worth it. It showed that he had a glioma brain tumor, and having an MRI-verified glioma is what made him eligible for the clinical trial at the University of Minnesota that has saved many dogs' lives. While Butkus was too far gone to be cured, it gave us valuable extra time with him. It was SO worth it...Please let me know if you'd like information on the study or just to talk....I've been keeping you and Rainey in my thoughts.
