The ever-increasing role that advanced visualization technologies play in today's radiology practice will be fully evident at this year's RSNA meeting in Chicago. Those seeking to keep up on the latest developments in 3D and computer-aided detection (CAD) will find a plethora of educational opportunities to choose from at McCormick Place.

3D will be well-represented in scientific sessions, with highlights including new automatic segmentation techniques and presentations on how 3D quantitative analysis can reliably measure coronary plaque. A number of education exhibits also will feature important applications for 3D.

In CAD, a broad range of scientific papers will be presented, covering the technology's use in a variety of lung applications, the prostate, the heart, the liver, and, of course, the breast. In virtual colonoscopy CAD, researchers are examining ways of improving the technology's utility and efficiency.

And interest continues to surge around the use of smartphones and Apple's iPad tablet computer for viewing medical images.

Refresher courses and other sessions

Of course, RSNA educational opportunities don't just end with scientific sessions and education exhibits. Advanced visualization topics will be covered in a number of refresher courses and other sessions as well.
