Radiation Dose Audit Reports to Reduce Radiation Exposure From CT Exams

The purpose of this study is to quantify variation in radiation dose levels across CT technologists, and determine the effectiveness of combining radiation dose audit reports and an educational seminar as a means to reduce the variation and level of patient exposure to radiation. The investigators expect the radiation dose audit reports and educational seminar will lead to reduced radiation exposure to patients by making technologists more aware of the risks of radiation exposure from CT exams and identifying technologists with higher radiation exams compared with their peers. The investigators expect the degree to which a technologist is concerned and aware about radiation exposure and cancer risk will be associated with adherence to radiation reduction protocols and the subsequent level of radiation their patients are exposed to when receiving a CT examination.
