1Radiological Science Department, College of Applied Medical Science, King Saud University, Riyadh, SAU.
本综述分析了沙特阿拉伯的儿科CT扫描辐射剂量,发现剂量指标的显著变化. 建立国家诊断参考水平 (DRL) 对于优化患者安全和标准化儿科CT成像至关重要.
科学领域:
- 医学物理 医学物理
- 放射学 放射学是一门学科.
- 儿科成像学 儿科成像学
背景情况:
- 诊断参考水平 (DRL) 对于优化医学成像中的辐射剂量至关重要.
- 由于儿童的放射敏感性,儿童CT检查需要特别注意.
- 目前沙特阿拉伯儿科CT的DRL缺乏全面的国家标准化.
研究的目的:
- 对沙特阿拉伯的儿科CT检查报告的诊断参考水平 (DRL) 进行审查和综合.
- 评估辐射剂量指标的变化,特别是CTDIvol和DLP,用于常见的儿科CT检查.
- 突出需要标准化协议和国家DRL来确保患者安全.
主要方法:
- 在主要的科学数据库 (PubMed,Science Direct,Google Scholar等) 进行了系统的文献搜索. ) 的情况.
- 报告沙特阿拉伯儿科CT检查DRL的研究被确定并评估.
- 从最初的31项研究中选择了8项相关出版物,用于提取和分析CTDIvol和DLP值的数据.
主要成果:
- 报告了大范围的平均剂量-长度产品 (DLP) 值:172-1881mGy.cm (大脑),27.3-458.9mGy.cm (胸部),94.5-790.1mGy.cm (腹部),78-236mGy.cm (腹部/盆地) 和94.2mGy.cm (CAP).
- 报告的平均体积计算断层剂量指数 (CTDIvol) 值有所不同:11.7-79.9 mGy (大脑),1.2-20.1 mGy (胸部),7.4-22.6 mGy (腹部),2.6-5.5 mGy (腹部/盆地) 和3.6 mGy (CAP).
- 在沙特阿拉伯的不同研究和地区报告的儿科CT剂量指标中存在显著的变化.
结论:
- 在沙特阿拉伯,迫切需要为儿科CT标准化成像协议和国家DRL.
- 实施和定期审查国家DRL可以帮助优化辐射剂量并提高患者安全.
- 建议改善技术人员和医生的培训,以确保儿童CT实践的一致性和安全性.

Computed Tomography
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...

Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...
