"I stopped him and told him that these [MRI] tests have never been done for her; that Michael had refused them."
I don't doubt that Michael Schiavo may have refused them. Terri Schiavo still has the thalmic stimulator implanted in what's left of her brain. An MRI is not a procedure that would be recommended as a result.
He was asked to have the implants removed.
He never did.
I wonder why.
