I signed up as a healthy volunteer for an MRI research study a few days ago, and today, I went in to get my brain scanned. Pretty cool, right? Apparently, I have a lot of grey matter… and a lumpy, but surprisingly round head.
By the way, if you live near a research hospital and wouldn’t mind being stuck in a small enclosed tube that makes loud noises for a little while, I highly recommend signing up for one of these studies. Unlike CT and PET, MRIs don’t expose you to any harmful radiation, so there are no health risks. Plus, the researchers will probably pay you a decent chunk of cash just to chill inside the machine (the study I did pays $30.00 an hour), and you’ll be helping to advance science in an important way.
