Introduction: Computed tomography is an imaging diagnostic method that plays an important role in diagnosing and treating diseases. Due to high radiation doses, which in
some cases are not properly applied, this imaging modality poses a risk to patients. Therefore, a system of measures has been established to reduce the negative impact of ionizing radiation exposure on health. One of these measures is the justification of procedures, which ensures that exposure provides more useful information than harm to the
patient, that the examination provides useful information, and that for each patient the most appropriate procedure is chosen. Purpose: The objective of this paper is to conduct a
systematic literature review to identify issues and potential improvements in the justification of procedures, as well as to analyze the state of justification in healthcare systems worldwide and in emergency situations. Methods: In this paper, we used the systematic literature
review method. We reviewed relevant professional literature, primarily in English. Sources were searched online and in scientific and professional databases such as PubMed and
ScienceDirect. Results: We found that the justification of procedures worldwide could be improved and that radiologic technologists could play a more significant role in
assessing justification of procedures. Discussion and Conclusion: A lack of knowledge among physicians regarding radiation protection, patient pressure, insufficient information on referrals, and failure to follow guidelines often lead to unjustified procedures. Proposed solutions include more frequent use of imaging guidelines, better public education on radiation effects, more involvement of radiologic technologists in the justification process, and enabling radiologists to access patients’ medical histories of ionizing radiation examinations.
