Standardizing CT scan protocols
A computerized tomography (CT) scan can yield a tremendous amount of diagnostic information, but it is also important to assess the amount of radiation a patient receives from these scans. In order to reduce the total amount of radiation, and to meet the terms of a new California law requiring the reporting of radiation exposure, health practitioners need to set standards that allow for high-quality diagnostic CT scans with a minimum amount of radiation. To create necessary exposure standards, a team including UCLA radiology researchers Dr. Michael McNitt-Gray and Dr. Christopher Cagnon was given a grant of $750,000 to create standard protocols for CT scans of all types which will balance radiation exposure and image quality. The team will also establish educational programs for all UC medical centers to create practice standards that could be used nationwide.
Reducing radiation from unnecessary CT scans
Many hospitals will automatically order a CT scan of any patient admitted with blunt chest injuries. Yet many of these scans, while exposing patients to ionizing radiation, may not provide any benefit. One reason so many patients receive these scans is that information that could help health professionals decide whether such scans are necessary is sc
