Background and Objective: The ongoing development of various medical imaging methods in hospitals and medical centers doubles the need to increase medical students' knowledge in regard with radiation protection. The present study was conducted to investigate the adequacy of medical physics course topics on medical students' knowledge regarding different medical imaging modalities and radiation protection in these examinations.
Methods: In this interventional study, 80 medical students who met the inclusion criteria were selected by simple random sampling and assigned to test and control groups using permutation blocks. In addition to medical physics sessions, a workshop on different medical imaging modalities and radiation protection was also held for the students in the test group. A researcher-made questionnaire on familiarity with radiation protection concepts was completed by the students before and after the workshop. Then, the level of knowledge and the score obtained from the questionnaire were analyzed.
Findings: After the workshop sessions, the knowledge level and the mean score of the questionnaire regarding familiarity with imaging modalities and radiation protection increased significantly in the test group compared to the control group (21.07±3.37 vs. 13.07±3.97) (p<0.05). Furthermore, in the areas of the nature of radiation, radiosensitivity of different body tissues, age-related radiosensitivity of patients, doses received by patients in different imaging tests, effects of ionizing radiation, as well as methods of patient protection against radiation and theoretical and practical foundations of the ultrasound modality, there was a significant difference in the level of knowledge of students between the test and control groups.
Conclusion: The results of this study highlight the valuable role of radiation protection education in reducing the risks of radiation, the most important result of which is reducing patient radiation exposure and reducing the negative effects of radiation.
