The CT is accurate, it just cant tell you whether what is left is comprised of living neurons, or the gliotic tissue that holds them together.
As for "can't wait"... are they going to remove it? I sure do wish they would, or at least give her another trial of therapy and re-evaluation. I don't like doing what they're doing with people unsure of her status.
If she gets a full review, I think that would be accurate. My fingers are crossed. I only want to do this right.
