Don’t have to. After 30+ years as a registered CT tech in Level 1 trauma centers in an urban environment on the midnight shift, I can ‘read’ the crap out of CT’s-neuro, body, and ortho. By the way, one of the ‘comparative’ images is actually a T1 MRI sagital reconstruction-not a CT.

Are you saying that Terri Schiavo had more or less liquid in her brain vs. working brain tissue?

Hydrocephalus is not the lone deciding factor for ascertaining brain viability. Image below is an example. Note no enlarged ventricles, although they have fresh blood shown on this one slice. Entrance wound right occiput, bone and metal fragments thruout both lobes, exit wound thru left frontal bone. (images are interpeted as if the patient is facing you) This type of penetrating wound are usually assigned to second year neurosurgery residents for 'practice' in the O.R. Survivability is zero. Yet, as shown, there is no hydrocephalus. It takes a team--neurosurgery, neurology, diagnostic radiology, to perform a battery of exams to find a diagnosis and impending outcome for the patient.
