That is not the issue.
Unfortunately, a CAT scan is of limited use in diagnosing PVS.
Why did Michael never permit a PET scan?
Why did he never permit an MRI?
She has never had either. Not once.
I find that baffling.
Have you seen the scan of her brain?
From another freeper who shall remain nameless by me:
Terri had every possible test repeated in 2002. But, they say, even their attorney tonight said, "he wont let them do an MRI, etc"
But they don't tell ya that to do that kind of test would zap that metal electrode planted in her brain.
(They also go on about "he did experiments on her!" even though, that was his last-ditch effort at stimulating her brain to function, and it was a technique even their own doctor Hammesfahr has said was a great idea!)
In 2002, they ran every other test - EEGs, CT scans, labs, etc., and 5 docs examined them and her to confirm what all her previous docs and therapists said - that she was both in PVS and that no current therapy could help her.
2 docs appointed by her husband, 2 by her parents, a court-appointed, and her regular doc testified. I read all 900+ pages of that transcript.
