Comparative Study of Level of Knowledge, Attitude and Performance of Radiologists, Medical Physicist and Radiographer Regarding Quality Control of Magnetic Resonance Imaging

Introduction: The aim of this study was to investigate the level of knowledge, attitude and practice of technicians and Radiologists, Medical Physicists and Radiographers in quality control of MRI devices. Methods and Material: 78 radiologists, medical physicists, and radiographers in seven medical centers of Hamadan were included in this study. Each member duties were determined based on the latest changes in the MRI quality control booklet designed by ACR. Moreover, three questionnaires for each group and one questionnaire related to the specifications of the device were prepared and completed by the relevant personnel. Data were analyzed using SPSS software version 16. Results: The results of Spearman correlation test show that there is a weak relationship between knowledge and performance (r= -0.005), knowledge with attitude (r= -0.032) and performance with attitude (r = 0.111) in radiographers. There is a weak relationship between knowledge and performance (r= 0.3), knowledge with attitude (r= 0.246) and performance with attitude (r = -0.109) in radiologists. In addition, there is a weak relationship between knowledge and performance (r= -0.177) in Medical physicists. Although there was a strong relationship between the level of knowledge with attitude (r= 0.559) and performance with attitude (r=-0.109) in medical physicists, this relationship was not statistically significant. Discussion and Conclusion: Factors including the presence of a complete quality control group, knowledge of performance, attitude of the group, appropriate and continuous training during service, availability of appropriate tools, mandatory rules for QA and the appropriateness of the number of patients to staff are the most important factors in control the quality of MRI.
