Rebecca Smith-Bindman

Rebecca Smith-Bindman is Professor of Radiology, Epidemiology and Biostatistics, Obstetrics, Gynecology and Reproductive Medicine, and Health Policy at the University of California, San Francisco School of Medicine. She is a clinical researcher with expertise in epidemiology, technology assessment, outcomes research, comparative effectiveness research, health services research, and dissemination and implementation sciences focused on imaging. Her research has focused on evaluating the quality, utilization, accuracy, predictive values and impact of diagnostic testing on patient health, and has quantified both the risks and benefits of medical imaging when used in different contexts and by different populations. Her research has included studies quantifying the use of medical imaging and quantifying to radiation doses associated with computed tomography scanning. Her interest, and expertise relevant to this meeting, concerns the use of low dose radiation in the area of health, and in particular, the growing exposure to low dose radiation from the large increase in the use of medical imaging and computed tomography (CT) over the last two decades. Exposure to CT in the US and Europe is the largest source of exposure to low dose radiation, and a growing source of radiation in the developing world as well. It is something that has fallen under the radar for many years, despite how rapidly the exposures are growing. And there is remarkably little oversight or quantification of exposures or risks in the U.S. She is currently leading several studies that assess and standardize the radiation dose used for CT scanning across a large number of institutions, in order to minimize doses, without loss of diagnostic accuracy. There are practical and easy steps to reduce doses and her research group has published several primary research papers on the topic, and she was the guest editor for an issue of the Journal of the American college of Radiology which was entirely focused on Radiation Dose Optimization for CT – providing very concrete and practical strategies for lowering patient exposures, particularly among children and vulnerable populations. She is also leading a large study quantifying the risks of cancer associated with medical imaging in children and adolescents.
