Overview & Program

Workshop Overview

The focus of this workshop will be on improving MR safety by examining contributions and improving communication between all stakeholders – from system and medical device manufacturers through academic researchers, regulators, clinical technologists, medical physicists and radiologists. This will include education on topics from the fundamental physics and physiology of discomforts and hazards in MRI, the current best practices in MR safety assurance from patient screening and handling through infrastructure and management. As well, considerations and challenges in ensuring safe conditions for imaging patients with medical implants, as well as ongoing improvements in techniques and technology for improving safety assurance into the future. The workshop will also be a forum for all stakeholders to discuss the latest developments with respect to MR safety and discuss current & future safety standards and testing methods. The workshop will include a mix of lectures, open discussions, poster sessions, and separation into parallel sessions for more specialized presentations and discussions.

Educational Objectives:

Upon completion of this activity, participants should be able to:

  • Describe the current knowledge of risks and potential hazards of MRI;
  • Explain current best practices in ensuring safety of patients, workers, researchers, and clinical staff in the MR environment;
  • Discuss current state of the art and associated challenges in ensuring MR safety of subjects with medical implants; and
  • Review upcoming techniques and technologies for improving MR safety in the future.

Target Audience:

Scientists, engineers, technologists/radiographers, medical physicists, radiologists, and administrators interested in MR safety.
