In radiography examination, it is common to encounter patients undergoing repeated X-ray exposure after the rejection of a film image due to poor image quality. This subjects the patients to unnecessary radiation exposure and extra cost for the facility. This fact has required to investigate the causes of film rejection in common X-ray examinations.
This study aims to obtain images, which are adequate for the clinical diagnostic purpose with minimum radiation dose to the patient in X-ray radiographic examination using film rejects analysis.
A prospective, crosssectional study design was carried out for 3 months. The film rejection rate data were collected using standardized checklist as recommended by the National Radiation Protection Authority and International Atomic Energy Agency. Daily recordings were compiled by frontline radiographers and senior physicians.
Data were analyzed descriptively using SPSS of version 23 software.
Overall rejection rate was 319 (10.02%) in 3183 X-ray exposures. The rejection rates by hospitals are 33.7% in Adwa, 13% in Aksum, 9.6% in Suhul, 9.2% in AbiAdi, 7.7% in Humera, 7% in Wukro, 4.3% in Lemlem Karl, and 2.9% in Alamata General Hospitals.
Rejected films were found to have been caused by numerous factors including incorrect exposure, poor technical judgment, patient motion, and improper film processing. Hence, strategies need to be developed within medical imaging departments to improve the situation.
在放射检查中，因图像质量差而拒收胶片图像后让患者接受重复X射线照射的情况很常见。这会使患者遭受不必要的辐射暴露，并给医疗机构带来额外成本。这一事实促使人们去调查普通X射线检查中胶片被拒收的原因。
本研究旨在通过胶片拒收分析，在X射线摄影检查中以对患者最小的辐射剂量获得足以满足临床诊断目的的图像。
进行了为期3个月的前瞻性横断面研究设计。使用国家辐射防护局和国际原子能机构推荐的标准化检查表收集胶片拒收率数据。每日记录由一线放射技师和资深医师汇编。
使用版本23的SPSS软件对数据进行描述性分析。
在3183次X射线照射中，总体拒收率为319次（10.02%）。各医院的拒收率分别为：阿德瓦医院33.7%，阿克苏姆医院13%，苏胡尔医院9.6%，阿比亚迪医院9.2%，胡梅拉医院7.7%，武克罗医院7%，莱姆莱姆卡尔医院4.3%，阿拉马塔综合医院2.9%。
发现拒收的胶片是由多种因素造成的，包括曝光不正确、技术判断不佳、患者移动以及胶片冲洗不当。因此，需要在医学影像科制定策略来改善这种情况。
