To achieve this goal, we carried out a prospective study involving 218 CT scans. These examinations focused on cerebral, thoracic, abdominopelvic and lum- bar spine acquisitions made in adults and cerebral only in children. We com- pared the median values of dosimetric indicators (CTDIvol and DLP) per acquisition with NRDs in the literature. During the course of this study, we found a dosimetric ratio lower than that of the NRDs for thoracic, abdomi- no-pelvic and lumbar spine CT scans in adults and a significant dosimetric exceedance for brain scans in adults and in children. These results encourage us to extend these dosimetric evaluations to other hospital structures in order to establish rigorous monitoring of dosimetric indicators and to respect the principles of radiation protection and good practice.
