Abstract:
Computed tomography (CT) is a key imaging technique in diagnostic radiology, providing highly sensitive and specific information. While its use has increased dramatically in recent years, the quantity and associated risks of radiation from CT scans present major challenges, particularly in paediatrics. The fundamental principles of radiation protection require that radiation quantities be as low as reasonably achievable and CT use must be justified, particularly for paediatric patients. CT radiation knowledge is a key factor in optimising and minimising radiation risk. The objective of this study was to analyse knowledge level, expertise, and competency regarding CT radiation dose and its hazards in paediatrics among radiologists in Saudi Arabian hospitals. A self-reported, multiple-choice questionnaire assessed the attitudes and opinions of radiologists involved in imaging studies using ionising radiation. Among the total respondents, 65% ± 13.5% had a good comprehension of the dangers of carcinogenicity to the patient resulting from CT scans, with 80% presuming that cancer risks were elevated. However, only 48.5%, 56.5%, and 65% of the respondents were aware of specific radiation risks in head, chest, and abdominal paediatric examinations, respectively. Regular, frequent, and specific training courses are suggested to improve the fundamental knowledge of CT radiation among radiologists and other physicians.
摘要:
计算机断层扫描(CT)是诊断放射学中的关键成像技术,提供高度敏感和特定的信息。虽然它的使用近年来急剧增加,CT扫描辐射的数量和相关风险提出了重大挑战,特别是在儿科。辐射防护的基本原则要求辐射量尽可能低,并且必须合理使用CT,特别是儿科患者。CT辐射知识是优化和最小化辐射风险的关键因素。这项研究的目的是分析知识水平,专业知识,以及沙特阿拉伯医院放射科医生对CT辐射剂量及其在儿科中的危害的能力。一个自我报告,多项选择问卷评估了参与电离辐射成像研究的放射科医师的态度和意见.在所有受访者中,65%±13.5%对CT扫描对患者的致癌性危害有很好的理解,80%的人认为癌症风险升高。然而,只有48.5%,56.5%,65%的受访者意识到头部的特定辐射风险,胸部,和腹部儿科检查,分别。常规,频繁,并建议开设专门的培训课程,以提高放射科医师和其他医师对CT辐射的基本知识。
