Rex,
You are WRONG to call me wrong. I have had a SPECT scan and I have seen several. I had the scan because I had already had an MRI and MRA of the optic pathways, and had a bilateral hononymous hemianopia and had the doc's stymied as to the cause. You can see blood actually moving as the scan is being done and you can see areas of narrowing or buldging of vessels.

Now, I don't know you or your credentials but I do know mine. And you sound dangerous with your misinformation and googling(?) of information. You see, I don't need to google info of this nature because I've either experienced it or been taught it.


Nuff said!
