Background and Objective: The increasing development of various medical imaging modalities in hospitals and healthcare centers has further emphasized the need to enhance medical students' knowledge of radiation protection. This study aimed to evaluate the adequacy of the medical physics curriculum in improving medical students' knowledge of medical imaging modalities and radiation protection in diagnostic procedures.
Methods: In this interventional study, 80 medical students who met the inclusion criteria were selected via simple random sampling and allocated into intervention and control groups using permuted block randomization. In addition to standard medical physics lectures, the intervention group attended a workshop on medical imaging modalities and radiation protection. A researcher-developed questionnaire assessing knowledge of radiation protection concepts was completed by students before and after the workshop. The collected data were then analyzed to compare awareness levels and test scores.
Findings: Following the workshop, the intervention group showed a significant increase in overall knowledge and mean test scores (21.07±3.37 vs. 13.07±3.97, p<0.05) compared to the control group. Significant differences were also observed in specific domains, including the nature of radiation, radiation sensitivity of different body tissues, age-dependent radiation sensitivity in patients, patient radiation doses across imaging modalities, biological effects of ionizing radiation, methods of patient radiation protection and theoretical and practical principles of ultrasound imaging.
Conclusion: The findings highlight the crucial role of radiation protection education in mitigating radiation hazards, with the most significant outcome being reduced patient exposure and minimized adverse effects of radiation. |
