Comparative Effectiveness Research Working Group

  1. Introduction: The goals of the AAR Comparative Effectiveness Research (CER) Working Group are to:
    • Provide resources to radiologists who want to take part in CER
    • Build CER research collaborations between institutions
    • Support CER projects that have the potential to get grant funded

On this page, you will find a collection of useful resources for radiologists who are interested in CER. We have organized this page into two sections. The first section, “Beginner level,” is for individuals who want to learn more about the basics of CER. This contains a collection of introductory CER articles. The second section, “Advanced level,” is for radiologists who want to pursue advanced training in CER and/or want to begin performing CER. This section contains links to available CER training programs as well as resources that can be used for research.

This page will be continually updated with new information and resources. If you have a resource that you think would be useful for CE researchers and is not included, please send your suggestion to [email protected].
