My husband recently had a pet scan. It found calcifications in his brain. What does this mean? When I "google" it, I'm taken to sites for brain cancer. He is being scheduled for a MRI. I also read that a CT scan is better than a MRI for detecting calcification. The nurse tried to tell me that brain calcification is "normal" but from what I've read it is not. He has been seeing dr's for several months now for symptoms. The main ones being nausea, weight loss and fatigue. He has headaches but nothing that tylenol hasn't relieved.
