I knew this was a special medical procedure when at least
half of the 30 or so ailments or conditions found in the hospital’s disclaimer
I had to sign were things I had never heard of. I did not want to ask. I just ticked the ‘no’ boxes and signed at
the bottom and handed the form and clipboard back to the clerk.
She then asked a curious question, “Can you hold your arms
up above your head?” Not thinking this could be particularly important, I
raised my hands above my head in a diving position with only slight strain in
my Parkinson’s-stiffened shoulders. Apparently, I passed the test. However, I
failed to ask what would prove to be a critically important question; “How long?”
It was not the first mistake I had made that morning. I had
followed the preparatory instructions to the letter, assuming when it said, “nothing
to eat or drink for four hours before”, it meant that I had to postpone taking
my Parkinson’s medications. I thought it best to tell the medical clerk not to
be alarmed at my shaking, and explained my unmedicated state. She obtained approval for me to take my
pills, but it was too late. The shaking had begun.
Of course, the tremors only increased when I saw the
technician arrive with a syringe and other paraphernalia. After searching for a
vein, he informed me that I was being injected with gadolinium. Gadolinium sounded
to me like the name of a small village occupied by hobbit-like creatures. Or,
perhaps, a newly-discovered galaxy. In fact, I was informed it is one of 17
rare earth chemical elements, and it is used in conjunction with an MRI
(Magnetic Resonance Imaging machine) because of the element’s magnetic
properties providing better definition for the images to be taken. I assumed it
was safe.
Having surrendered up my hearing aids, asking any further
questions, or at least hearing any answers, was likely to prove challenging, if
not impossible. Patting the platform, indicating I was to lie down on a somewhat
uncomfortable horizontal frame, the technician moved my arms above my head into
the recently demonstrated dive position. Speaking loudly in one ear, he asked
what I assumed was a rhetorical question; “Can you hold this position for the
next 35 minutes?” How was I supposed to know? I do not recall ever having to maintain
that position for 35 minutes.
I discovered a long time ago that I am not claustrophobic
(that had been one of the questions on the disclaimer I had marked no”). And it’s
a good thing because I was slid into the MRI tube feet first, arms in the dive
position, looking like I was practising for the one-man luge event in the
Olympics, except for the arms. Hearing various clicking sounds, I knew we were “locked
and loaded”. I realized then that 35 minutes would be a very long time.
Squeezed into place, unable to move, the procedure began. What
followed was a series of very loud sounds; something like a cross between banshee
screams and intermittent air raid siren. In advance of each noisy invasion, there
was a computer-generated voice, which seemed in my deafened state to whisper, “Breathe
in. Hold your breath.” I wanted to ask, “How long?” But I was certain I wouldn’t
have heard the answer. So I obeyed, breathing in all the oxygen I could, given
the extremely cramped conditions, and breathing out when told to do so. All the
while, the machine emitted computerized screams.
After what seemed like a lot longer than 35 minutes, I was
withdrawn from the MRI “compression cylinder”. Despite aching shoulders, a couple
of needle stab wounds, I knew the answer to the questions: “Yes, I can hold my
arms over my head in the dive position for 35 minutes.” But please don’t ask me
to do so.
