Dr. Rebecca Smith-Bindman, the director of the Radiology Outcomes Research Laboratory and a professor of epidemiology and biostatistics at the UCSF School of Medicine, joins Lisa Dent to further discuss the effect that medical scans have on patients. Dr. Smith-Bindman warns of unnecessary full-body MRI scans, warning that there is “more harm than benefit.”

Last week, Dr. Smith-Bindman discussed the results of her team’s study that shows that the continued practice of unnecessary CT scans could account for five percent of new cancer diagnoses.
