@phdthesis{oai:nagasaki-u.repo.nii.ac.jp:00003164, author = {吉田, 浩二}, month = {Mar}, note = {Purpose: The accident at the Fukushima Daiichi Nuclear Power Plant has raised concerns about radiation exposure, including medical radiation exposure such as X-ray and CT, in residents of Fukushima. Materials and methods: We compared the numbers and the ratio of outpatients less than 10 years old who underwent imaging examinations [e.g., CT, X-ray, MRI, ultrasonography (US), etc.] at Fukushima Medical University hospital in Fukushima, Japan before (April 1, 2008-March 31, 2011) and after (April 1, 2011-March 31, 2014) the accident. Results: The number of outpatients less than 10 years old decreased after the accident. The number of outpatients less than 10 years old who underwent CT and X-ray examinations also significantly decreased after the accident (p < 0.001, p < 0.01, respectively). Conclusion: Our results suggest that the number of pediatric radiological examinations decreased after the accident in Fukushima. We should continue to communicate with patients and their families to ensure that they understand the risks and benefits of radiological imaging in order to overcome their concerns about the nuclear disaster., 長崎大学学位論文 学位記番号:博(医歯薬)甲第832号 学位授与年月日:平成28年3月18日, Author: Koji Yoshida, Naomi Hayashida, Yoshiko Fukushima, Akira Ohtsuru, Takashi Ohba, Arifumi Hasegawa, Hisashi Sato, Fumio Shishido, Kiyotaka Yasui, Atsushi Kumagai, Takeshi Yusa, Takashi Kudo, Shunichi Yamashita, Noboru Takamura, Citation: Japanese Journal of Radiology, 33(10), pp.619-626; 2015, Nagasaki University (長崎大学), 博士(医学) (2016-03-18)}, school = {Nagasaki University (長崎大学)}, title = {Changes in radiological imaging frequencies in children before and after the accident at the Fukushima Daiichi Nuclear Power Plant in Fukushima Prefecture, Japan}, year = {2016} }
