Why Hasn’t an MRI been done for Terri?

I have spent the past ten days recruiting and interviewing neurologists who are willing to come forward and offer affidavits or declarations concerning new testing and examinations for Terri. In addition to the 15 neurologists’ affidavits Gibbs had in time to present in court, I have commitments from over 30 others who are willing to testify that Terri should have new and additional testing, and new examinations by unbiased neurologists. Almost 50 neurologists all say the same thing: Terri should be reevaluated, Terri should be reexamined, and there are grave doubts as to the accuracy of Terri’s diagnosis of PVS. All of these neurologists are board-certified; a number of them are fellows of the prestigious American Academy of Neurology; several are professors of neurology at major medical schools.

So how can Judge Greer ignore the opinions of so many qualified neurologists, some of whom are leaders in the field? The answer is that Michael Schiavo, his attorney George Felos, and Judge Greer already have the diagnosis they want.

Terri’s diagnosis was arrived at without the benefit of testing that most neurologists would consider standard for diagnosing PVS. One such test is MRI (Magnetic Resonance Imaging). MRI is widely used today, even for ailments as simple as knee injuries — but Terri has never had one. Michael has repeatedly refused to consent to one. The neurologists I have spoken to have reacted with shock upon learning this fact. One such neurologist is Dr. Peter Morin. He is a researcher specializing in degenerative brain diseases, and has both an M.D. and a Ph.D. in biochemistry from Boston University.

In the course of my conversation with Dr. Morin, he made reference to the standard use of MRI and PET (Positron Emission Tomography) scans to diagnose the extent of brain injuries. He seemed to assume that these had been done for Terri. I stopped him and told him that these tests have never been done for her; that Michael had refused them.

There was a moment of dead silence.

"That’s criminal," he said, and then asked, in a tone of utter incredulity: “How can he continue as guardian? People are deliberating over this woman’s life and death and there’s been no MRI or PET?” He drew a reasonable conclusion: “These people [Michael Schiavo, George Felos, and Judge Greer] don’t want the information.”

Dr. Morin explained that he would feel obligated to obtain the information in these tests before making a diagnosis with life and death consequences. I told him that CT (Computer-Aided Tomography) scans had been done, and were partly the basis for the finding of PVS. The doctor retorted, “Spare no expense, eh?” I asked him to explain the comment; he said that a CT scan is a much less expensive test than an MRI, but it “only gives you a tenth of the information an MRI does.” He added, “A CT scan is useful only in pretty severe cases, such as trauma, and also during the few days after an anoxic (lack of oxygen) brain injury. It’s useful in an emergency-room setting. But if the question is ischemic injury [brain damage caused by lack of blood/oxygen to part of the brain] you want an MRI and PET. For subsequent evaluation of brain injury, the CT is pretty useless unless there has been a massive stroke.”

Other neurologists have concurred with Dr. Morin’s opinion. Dr. Thomas Zabiega, who trained at the University of Chicago, said, “Any neurologist who is objective would say ‘Yes’” to the question, “Should Terri be given an MRI?”

But in spite of the lack of advanced testing, such as an MRI, attorney George Felos has claimed that Terri’s cerebral cortex has “liquefied,” and doctors for Michael Schiavo have claimed, on the basis of the CT scans, that parts of Terri’s cerebral cortex “have been replaced by fluid.” The problem with such contentions is that the available evidence can’t support them. Dr. Zabiega explained that “a CT scan can’t resolve the kind of detail needed” to make such a pronouncement: “A CT scan is like a blurry photograph.” Dr. William Bell, a professor of neurology at Wake Forest University Medical School, agrees: “A CT scan doesn’t give much detail. In order to see it on a CT, you have to have massive damage.” Is it possible that Terri has that sort of “massive” brain damage? According to Dr. Bell, that isn’t likely. Sometimes, he said, even patients who are PVS have a “normal or near normal” MRI.

So why hasn’t an MRI been done for Terri? That question has never been satisfactorily answered. George Felos has argued that an MRI can’t be done because of thalamic implants that were placed in Terri’s skull during the last attempt at therapy, dating back to 1992. But Felos’s contention ignores the fact that these implants could be removed. Indeed, the doctor who put them in instructed Michael to have them removed. Michael has never done so.

The most obvious possible explanation for what would otherwise be inexplicable behavior is that Michael Schiavo, George Felos, and Judge Greer don’t want to admit any information that would upset the diagnosis they already have. Dr. Morin, when told that Michael had refused an MRI, and that Judge Greer had confirmed the decision, said: “He refused a non-invasive test? People trying to do the right thing want the best and most complete information available. We don't have that in Terri’s case.” Dr. Bell agreed with this assessment, saying, “It seems as though they’re fearful of any additional information.” -
