Determining the Rate of Change in Exposure to Ionizing Radiation From CT Scans: AÂ Database Analysis From One Hospital

Exposure to ionizing radiation from these examinations was reduced at one institution because of reduced volumes of procedures and the reduction of each procedure's effective dose through new protocols and technologies. Although both the volume reduction and dose reduction strategies contributed to the reduced exposure, it seems that investments in implementing the protocols and new technology had the greatest effect on future cancer risk.
