• 2023:03 A novel method for retrospective analysis regarding appropriateness of radiological examinations

  examinations, especially computed tomography, has increased in recent decades and it is essential that this increase is justified and contribute to a better care of the patients. There are many reasons to refrain ... ionising radiation. In the radiation protection system, this is expressed as the justification principle and is of particular importance for medical exposures because dose limits for this type of exposure are...
