Had an MRI today (Magnetic Resonance Imaging), which is a little
like living through an eruption on Mt. St. Helens while lying at
the summit.
It is instructive and historically redolent. This was a “closed”
MRI. They omit “casket” from the “closed” but the awesome
resemblance is immediately apparent. “Keep your eyes closed,” was
the best advice I’d gotten, but which I ignored once inside the
tube. Sure enough; there was the ceiling, or casket’s roof,
inches from my nose. And I had been given a little device that
could signal the operator that I had had enough and wanted out,
pronto. It reminded me of the other caskets used in the
pre-coroner days of jolly old England in which a string was
attached to the supposedly-deceased hand that led up to a little
bell on the surface of the earth. Should the unconscious victim
of a premature burial suddenly awaken, all he had to do was
jerk the string and ring the bell. Hence the phrase: “Does that
ring a bell?”
There was a great-Aunt who beat them to it in the last century
and was discovered sitting up in her casket in her living room.
But I digress.
An MRI victim can usually select music, which becomes inaudible
when the first shot of magnetism shudders through the machine,
something like a .50 caliber machinegun being operated near one’s
ear. What is happening, we are told, is the alignment of the
hydrogen atoms in the water in one’s body that will produce an
image on the film. After some twenty minutes of varying sounds, a
technician’s voice commands, “Don’t move, now. I’m taking
you out to inject the contrast in your arm.” The roof slowly
slides past your nose and you are returned to the end of the
machine, where the contrast fluid is injected and you are moved
back into the casket for another fifteen minutes or so of
thunderous noise, which again blots out the piano music you have
ordered. Now and then the disembodied voice intones, “Now, three
and a half minutes of this,” and the sound is resumed, until
finally the voice declares, “All finished.” Images of a tiny bell
ringing unheard in an English churchyard recur.
I am told I may retrieve my clothing and be given the images that
a doctor had ordered. As I take them I cannot resist explaining
to the technicians, “You know, that water-boarding at Guantanamo
that got us in such trouble was totally unnecessary. All they had
to do was ship one of these MRI machines down there.”
Nobody laughed. And neither did the receptionist when I told her
that if ever I reappeared in the office she was to call the
police.
