Even though the theme for RSNA 2010 was "personalized medicine," exhibitors and attendees alike were continuing to discuss and debate the hot topic of last year's show - dose reduction.

Meaningful use and its impact placed a distant second for the buzz heard around the show floor, but interest will undoubtedly increase in the months to come as roll outs and requirements emerge.

Still, discussions of dose reduction carried the day and it was addressed in a myriad of ways. From talk of additional education and certification for radiologists to software and equipment updates, all intended to better monitor and control dose, all avenues were being explored at the show.

With troubling stories of excessive exposure emerging at nearly a weekly rate and even the FAA feeding the fire with the introduction of, and subsequent debate about, full body scans at airport security checkpoints, it wouldn't come as a surprise to find RSNA 2011's big buzz to be about dose reduction. But that's a whole new ball game.
