I think Kim's current doc is looking to do this annually, but there are potentially unique reasons for his thinking. One thing for sure, it's a big deal to have comps and to be able to compare them chronologically. I'd highly recommend, brain and spine. If you one day (and I hope you never need to) find your doctor wondering about that spinal MRI in 2009, you can say, "yup, you're in luck, I had one of those". just my opinion. Ken
