투시 조영 검사 시 환자 선량 관리를 위한 진단참고선량 구축에 관한 연구 (UGI, Esophagography 기준)
Fluoroscopy examinations for the management of patient dose study on the establishment of diagnostic reference level (UGI, Esophagography standards)
eference levels based on the original set of guidelines and fluoroscopy, through the provision of medical radiation exposure reduction and further optimization of Defense to realize that is intended. 359 names in our hospital underwent Esophagography 302 patients who underwent UGI average fluoroscopy time and number of images to calculate the average 21 cm Acryl phantom dose for 10 seconds and 20 seconds, average area dose and the area dose of 1 spot image, 5 spot consecutive images by measuring the patient dose and third quartile of the mean area dose was set seonryangin reference dose. Esophagography average patient dose was set to 30.05 Gycm2, DRL was set at a 25.37 Gycm2. Average dose of UGI patients were selected as 45.33 Gycm2, DRL was set at a 34 Gycm2. UGI patients with established average dose recommended in the 2008 national recommendation from the UGI examination with a dose of less than 49.7 Gycm2 seonryangin is evaluated. This Note examines the dose of self-aware through education recognizes the importance of dose reduction and examine if their efforts and further reduce patient dose could achieve optimization of the medical exposure is considered.
