Analysis here of Terri's CT scan from 1996 -

In a nutshell -
"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."
"If you starve this woman to death it would be, in my professional and experienced medical opinion, the equivalent of starving to death a 75-85 year old person. I would take that to the witness stand."
Of course, the whole discussion about the "shunt" ignores the fact that Terri had an electronic stimulator placed in her brain prior to that scan. Even the quacks who testified in the case picked that up.
