Medical Radiation Induced Cancers

The pilot project described in the application will allow the collaborative team to assemble preliminary data from the eight Cancer Research Network (CRN) sites needed to apply for a multi-site R01, with a schedule submission date of October 2009. In addition, the data collected will result in at least three manuscripts describing (1) patterns and variability of medical imaging over time, (2) patterns of radiation exposure associated with medical imaging over time, and (3) variation in radiation exposure associated with several common types of computed tomography (CT) examinations. The R01 will identify factors that contribute to variation in the utilization of medical imaging over time; will quantify variation in radiation dose associated with specific CT examinations and identify factors that contribute to this variation; and will empirically estimate the increased risk of radiation-sensitive cancers among patients associated with medical radiation exposure due to imaging.
