[QUOTE=Possegal;558922]I've only heard of that when they are imaging the brain, since the sugar's role is to highlight very active areas and the brain is very active to begin with and would be more so with 'stimulation' such as being able to read and look around and such.

since the cancer cells absorb the sugar and are highlighted, I would bet the reasoning is the same- they don't want the little suckers moving around too fast. As far as I know, all they do is the breast scans but your theory about them not being able to change the routine according the the scan is probably accurate. As for taking a book I hate- I can zone out on any spoken material even if I love the book.

Thanks for your good wishes.
