Radiation doses from common CT procedures vary widely and are higher than generally thought, raising concerns about increased risk for cancer, according to a new study led by UCSF imaging specialists.
"In day-to-day clinical practice, we found significant variation in the radiation doses for the same type of computed tomography procedures within institutions and across institutions," said lead investigator Rebecca Smith-Bindman, MD, a professor of radiology at UCSF. "Our results highlight the need for greater standardization because this is a medical safety issue."
