Rsna News Scientific Educational Program

  1. 1. Scientific, Education Programs Propel RSNA 2010 to a New Level Patient-tailored care, dose-reduction efforts, healthcare policy and emerging technology are among the compelling issues slated to make headlines at RSNA 2010. Along with the latest in education exhibits and scientific presentations, attendees can choose from a diverse roster of refresher courses, self-assessment modules (SAMs), applied science, integrated science and practice sessions, and workshops encompassing every specialty.

Small, M.D., Ph.D., said this year’s gastrointestinal exhibits have a particularly strong representation of MR techniques. “They include the use of high-field magnets, advanced imaging techniques including diffusion-weighted applications and investigation of varied contrast materials,” he said. “Enteric imaging using both multidetector-row (MD) CT and MR techniques are popular topics as well.” Presentations reflect a strong interest in pancreaticobiliary problem solving and multi-energy MDCT, Dr. Small said. Genitourinary Radiology/ Uroradiology MR imaging techniques are undergoing further refinement with high interest in prostate imaging, said Erick M.
