Tracking Radiation Doses from Medical Diagnostic Procedures

December 14 @ 10:00 am - 12:00 pm EST

Virtual Event Virtual Event

The Nuclear and Radiation Studies Board of the National Academies will host a two-hour webinar on December 14 to discuss the pros and cons of tracking radiation doses from medical diagnostic procedures and possible implications.

The use of medical diagnostic procedures has benefited the care of most patients. However, it is accompanied by growing concerns about the risks associated with diagnostic computed tomography (CT), fluoroscopy, and nuclear medicine imaging exams that utilize ionizing radiation. A number of initiatives in radiation safety in medicine aim to provide higher quality clinical management of patients and to ensure that reasonable steps are taken to keep the exposures as low as possible without compromising diagnostic efficacy. The idea of tracking radiation exposures from medical diagnostic procedures as a means of individual dose monitoring and risk assessment to patients has been debated over the years and more recently national and international organizations have issued statements with opposing views.
