Terri Schiavo's CT scan another physicians opinion
http://www.freerepublic.com/focus/f-news/1375968/posts
A physician at a credible physicians website has analyzed Terris CAT scan and concludes that it has been grossly misrepresented. There is some cerebral atrophy, but it is a completely inaccurate to characterize it as bag of water. Furthermore, the author states that
the most alarming thing about this image, however, is that there certainly is cortex left. Granted, it is severely thinned, especially for Terri's age, but I would be nonplussed if you told me that this was a 75 year old female who was somewhat senile but fully functional, and I defy a radiologist anywhere to contest that.
In fact, the entire field of diagnosing persistent vegetative state or PVS is fraught with inaccuracy. Recent studies have shown the rate of misdiagnosis to be as high as 37% or even 43%. PVS is a clinical diagnosis, meaning that it depends on the subjective judgment of the examining physician. Experts in the field cannot even agree on the usefulness of diagnostic imaging.
