As far as where to get CK, I asked Dr. Medbery that question on the Cyberknife forum, and he said that any CK facility, even a new one, should be fine, as long as the staff has training on CK and some prior experience with radiation treatment - which most or all of them do. Of course, I'm trying for CK at Stanford anyway, but like Bruce, I have folks to visit there anyway.
I didn't realize you could get your MRI on CD at the time, but a few weeks later, when my ENT told me I could, I phoned up the place, and they had it ready to go the next morning. I think the radiologist had the report written up within 2 or 3 days of the scan.
Sandra, I know the feeling, a change in hearing level prompted me to consider treatment rather than waiting any longer. It just seemed to me that if the hearing was going, the time for action was at hand. You will find the right decision for you in due course.
And Anne Marie, way to go with the squeaky wheel bit, you go girl. Good luck with the MRI.
