Thematic course: patient radiation protection

The ratio benefit/risk of radiological examinations, especially with the multislice scanner cannot be ensured only if the principles of justification and optimization are rigorously respected. The justification relies on the reference to the guide of the appropriate use of imaging examinations and compliance with the Public Health Code which requires a written information exchange between the applicant and who will realizes the examination. The optimization relies on the dosimetry evaluation of our practice and the comparison with the diagnosis reference levels, to realize the examinations at the radiation lowest cost. the stakes are the insurance does not harm our patients, the rehabilitation of the radiologist in his role of consultant rather than performer and the protection against eventual legal consequences.
