re: Tebow Update .....latest at 12:24

There are three classes of traumatic brain injury: mild, moderate and severe.

Mild TBI's do not show up on a CT scan nor on a conventional MRI (1.5 tesla). They will show a hemorrhage or a hematoma, but will not show a more subtle injury (like a diffuse axonal injury). He would need a 3.0 tesla MRI to show really good detail, but it is unlikely they would use one given his symptoms. UK Medical school probably has the only 3.0 MRI in the Lexington area.

Hopefully, at worst it is a mild TBI. And hopefully, the vomiting was from the flu. Tebow needs to be observed, but most people have a full recovery from a mild TBI.
