MRI: The Sounds of Scanning

After my initial diagnosis and prior to meeting with a surgeon, I was sent for an MRI so the medical team could get a clearer picture of the size and spread of the cancer in my breast. My appointment was at 8 am, and I sat sleepily in the chair across from the administering technician, unsure what to expect. I knew an MRI used magnets, and I was pretty sure I was going to have to spend some time inside a big tube, a fact that made my claustrophobic self shudder.

The technician, named Steve—a good omen, I thought, his sharing my husband’s name—told me that first he needed to ask a series of questions to make sure I didn’t have any metal on or in my body. I’d left my jewelry at home as instructed, so I didn’t think there was an issue, but the inquisition was protocol.

MRI-Steve clicked a few keys on the computer in front of him. “Do you have anything inside your body that you were not born with?”

Later, I’d wish I’d been quick enough to offer “cancer.” Instead, I said, “Um, contact lenses?”

He chuckled a little.  “Good answer.”

He clicked another key and proceeded to the next question. No, no pacemaker. No artificial joints. No piercings except my ears, no tattoos (some ink has metallic compounds), and no, I’ve never been a welder. Wait, what? Apparently welders often have tiny traces of metal in their eyes, and if they do, the machine can pull the traces out and blind the welder in the process. Ow.

Finally MRI-Steve asked what kind of music I liked. While I was in the machine I would hear some noises—a kind of clunking, and then a series of buzzes. “Your test will only last 30 minutes or so, so it’s not too bad,” he said. “Some can take an hour or more.” Patients were provided with headphones hooked up to Spotify or Pandora to mitigate the noise.

“Oh, well, I like the Indigo Girls,” I said. “I just saw them in concert last night.”

I wondered what he’d have said if I answered “heavy metal.”

After inserting a magnet-friendly IV via a needle that left behind only a tiny plastic tube, MRI-Steve walked me back to the dimly lit room that housed the MRI machine, an impressively large and imposing white, plastic extra-deep donut with a gurney-like table jutting out from the near side of the opening. I thought it odd they were playing club music, techno with a heavy, steady bass beat: ka-thunk, ka-thunk ka-thunk. Then I realized the rhythm was coming from the machine. If those were the clunks MRI- Steve had referred to, the noise wasn’t too bad.

Steve left me with his assistant Shevonne to help me get settled on the table. Lightly padded and lined with a sheet, it was shaped like a body. Close in, it looked like a sleeping capsule in an old sci-fi film, or maybe a mummification crypt with a shroud. Shevonne pointed to two pronounced breast-shaped imprints. I was to position myself so that each of my breasts hung down into one of the cups, where cameras were located. I decided not to think too much about how that worked as I climbed aboard. At Shevonne’s direction, I stretched my arms out in front of me, like Supergirl in flying mode.

I was given a squeeze-bulb call button to hold in my left hand, and Shevonne wrapped some of the tubing for the IV around my thumb on the right. Midway through the procedure I’d be given a contrast agent, and the machine would track its progress through my veins. The face cradle allowed me to breathe freely and had a long slit to accommodate opening my eyes. When I’d told MRI-Steve my fear of small spaces, he’d reassured me that since I’d be facedown and looking into a mirror, I’d be less aware of being inside the tube. Shevonne placed the earphones on my head and asked if anything tickled or itched. Once inside, no scratching allowed.

I felt the gurney lift up a few inches, then move forward. I peered down through the eye slit. I couldn’t see myself, so maybe I’d misunderstood about a mirror. As I slid further into the machine, it looked as if the floor dropped away below me, revealing another small room below.

Within seconds, I was dizzy with vertigo.

MRI-Steve’s voice came over the loudspeaker. “Everything okay?”

My head spun. “I’m really, really dizzy,” I said. “Is that normal?”

“Um, no, not really,” he said. There was a pause. “Sometimes if you didn’t eat breakfast…?”

Slowly the dizziness abated. “I think it’s starting to subside,” I said. The Indigo Girls’ “Closer to Fine” played through my headphones. “I went to the doctor. I went to the mountains…”

“We’re going to start your test now. It will be loud, so don’t be startled.”

“Okay,” I said. I closed my eyes and pictured the finale of the previous night’s concert, the euphoria I’d felt singing along with the Girls and the audience to the song now playing in my ears.

Then a fire alarm went off.

MNAAH. MNAAH. When MRI-Steve had said “buzz” and “loud,” I had not translated it as “You know, like that fire alarm that used to make you leap out of bed, adrenaline coursing and heart pounding, for 3 AM college dorm fire drills.” MNAAH. MNAAH. MNAAH. It continued for another 30 seconds. Then it stopped. Music returned. A second round. Musical interlude. Then another set of noises, with a higher pitch and faster pulse, an old-fashioned dial tone on steroids, quickly supplanted by a light bamboo-stick percussion that morphed into an electronic chicken, bok-bok-bok-bok-BAWK on the right, then loud bamboo sticks, more buzzy dial tone BEEP-BEEP-BEEP, more soft bamboo and the chicken circled around to my left, bok-bok-bok-bok-BAWK ticketa ticketa ticketa BEEP-BEEP-BEEEEP. Caesura. “The less I seek my source for some definitive, the closer I am to fine.”

Maybe they ensconced you in a tube to keep you from fleeing the racket. I felt like I’d landed somewhere between a bad carnival funhouse and an auditory version of Ludovico’s re-programming technique in A Clockwork Orange. Another cycle of the same, then another, each a little longer than the one before. In between, music played through the headphones: a tinny war protest song about not marching no more, some traditional bluegrass pickin’. Not my fave, but preferable to two minutes of fire alarm. MNAAH. MNAAH.

MRI-Steve’s voice filtered in. “We’ve put the contrast in, so two more minutes of pictures, then you’ll be more than halfway done.”

Halfway? I was reminded of my hiker friend Jeff’s comment about climbing steep mountains: “Usually when you think you’re almost there, it really means you’ve only gone halfway.”

A coolness spread from my right arm down to my hand, and for a few moments an astringent, metallic taste filled my mouth and stung my nostrils, then disappeared. As the cool crept up both arms and dissipated, the fire alarm sounded again. When it stopped, an Old Navy commercial was playing.

“Nine minutes,” MRI-Steve said.

I tried to breathe evenly. Jeff Buckley sang “Hallelujah,” and the electronic chickens circled once more around my head.

Once upright and retying my robe, I put it together: a mirror in the head cradle gave the illusion of a disappearing floor, an empty space below the machine, to counter claustrophobia. As my body moved forward and back on a flat plane, my eyes perceived I was moving up and down: ergo, vertigo. It really was a sort of funhouse trick.

Queasy and rattled, I headed to the dressing room. It would be several days before we’d find out the results of the imaging. It was too bad that sound waves couldn’t dissolve cancer cells the same way they did kidney stones—I’d be well on my way to cured. In the dressing room mirror, my forehead sported a bright red imprint from the pressure of the cradle, while my body, everywhere but my breasts, was marked with wrinkles from the sheet.

My Steve raised his eyebrows at my unsteadiness when I emerged. I wanted to warn the other guy sitting there, awaiting his own test, but how exactly do you explain being assaulted by the squawks of unseen robot birds?

I was sorely in need of a nap. I just hoped the chickens wouldn’t follow me into my dreams.
