I didn’t think it would be that difficult. But as the technician placed the X-ray shield over my knee, handed me the headphones, and left the room, a sense of uncertainty surrounded me like the MRI machine I was lying in. Even though my head and shoulders remained outside the tunnel, I felt trapped. My mind raced, as I discovered flight responses never before encountered. Watching the countdown clock on the upper part of the machine, I wondered if my heart and mind would quiet down or if the next few minutes would include me jumping out of the machine in a mad fit of panic.
