Radiology, OMG! If you haven't shadowed anyone, the only reason you might want to go into it is because diagnostic radiologists and interventional radiologists have the coolest
toys (let's not mention the hours or no one will think that you want it for the right reasons).
You've wanted to do it ever since you excelled with
Where's Waldo and
I Spy (pattern recognition). Being ambidexterous and having an aptitude for video games operated with a job stick are a plus for the interventionalists. You want to make patients lives better through minimally invasive procedures and quicker, painless and safer imaging techniques. You also like the idea of collegial relationships with surgeons who need images to maximize their effectiveness in the OR. (Have you seen some of these 3-D images that can be made with CT).
