The 100th Meeting Of RSNA Just Happens To Be Spiral CT's 25th Anniversary

The 100th meeting of RSNA just happens to be spiral CT's 25th anniversary, and in 2014 both are in fine shape. CT's star wasn't always rising, of course. Twenty-five years ago, the modality was all but left for dead as MRI was rising to prominence.

It was the invention and application of spiral CT, first presented in clinical studies at the 1989 RSNA meeting, that turned things around and put CT on track for today's extraordinary achievements, according to medical physicist and CT pioneer Willi Kalender, PhD.
