As long as you’re aware of what radiologists do, you only need to have been an imaging patient a time or two to appreciate how much value the specialty adds to U.S. healthcare. Personally, of course, I know what rads do because of my work. But I also have plenty of firsthand experience to draw from. Thinking back, I count four MRIs, two CTs, one diagnostic ultrasound and a dozen or so x-rays. At least.
