Ages ago - Michael won't allow it.
I heard one of the Doctor's supporting her death admit last night that he only examined her for 45 minutes and he said that she's NEVER had a PET or and MRI and I think she's only ever hasd 1 CAT Scan. Imagine! They've determined her life is worthless and she has no hope of recovery without ever even examining her!
God bless Jeb...I've read alot of unfair and unfounded criticism of him lately but he's been a champion of Terri and her family all along.
