I have been doing research on different scans. I found the SPECT scan is supposed to be able to detect brain damage because it scans blood flow in the brain. The cost is still high around 4000.00 for two scans one resting the other thinking I guess for lack of a better term. I emailed a clinic in Colorado and they returned my call and we discussed it. I am thinking about getting it done if I can find a reasonable reliable facility here in Minnesota.
