Quality Control of Medical Imaging 1 Joon-Il Choi, M.D., Dong Gyu Na, M.D., Hak Hee Kim, M.D. 2, Yong Moon Shin, M.D. 2, Kook Jin Ahn, M.D. 3, Jae Young Lee, M.D. 1 Department of Radiology, Seoul National University, College of Medicine, and the Institute of Radiation Medicine 2 Department of Diagnostic Radiology, Asan Medical Center, University of Ulsan, College of Medicine 3 Department of Diagnostic Radiology, St. Mary s Hospital, The Catholic University of Korea Medical imaging is the one of the most important diagnostic tools of modern medical science and quality control of the medical imaging is already systemized in the advanced countries. However, in Korea, quality control of medical imaging has not been properly performed until now and low quality examinations have been done without any regulation. The Korean Radiological Society, as society of supervision of medical imaging, has emphasized the importance of quality control and in 2003, the law for the quality control of medical imaging was made. In conformity of the law, the regulation of the quality control of medical imaging will commence, but this is just the beginning and there are still many tasks left for settling down and expanding the range of the quality control of the medical imaging. We reviewed the history of the quality control of medical imaging in Korea and explained the particulars of mammography, fluoroscopy, computed tomography and magnetic resonance imaging. We also looked into future prospect and tasks of the quality control of medical imaging.
