Abstract：
The objective of this study was to evaluate patient knowledge and understanding of ionising radiation and dosage, as well as the accompanying risks related to computed tomography scans. A total of 412 outpatients who underwent computed tomography (CT) scans were surveyed to assess their understanding of radiation dose and exposure risks. CT was correctly classified as an ionising radiation by 56.8% of the respondents. More than half of the patients reported that a CT scan increases the probability of inducing cancer. Awareness of varying radiation doses in different CT exams was noted in 75.2% of patients, but only 21.4% reported having discussions with their physician about radiation dose. Gender, age and employment were significantly correlated with knowledge levels. The survey findings indicate a limited understanding of the hazards associated with ionising radiation used in CT scans, highlighting a need for increased awareness and education on radiation protection to ensure informed consent.
摘要：
这项研究的目的是评估患者对电离辐射和剂量的知识和理解，以及与计算机断层扫描相关的风险。对412名接受计算机断层扫描（CT）扫描的门诊患者进行了调查，以评估他们对辐射剂量和暴露风险的理解。56.8％的受访者将CT正确归类为电离辐射。超过一半的患者报告说CT扫描增加了诱发癌症的可能性。75.2%的患者注意到不同CT检查中不同辐射剂量的意识，但只有21.4%的人报告与医生讨论了辐射剂量。性别,年龄和就业与知识水平显著相关。调查结果表明，对CT扫描中使用的电离辐射相关危害的了解有限，强调需要提高对辐射防护的认识和教育，以确保知情同意。
