这项研究建立了国王阿卜杜拉齐兹大学医院的核医学局部诊断参考水平 (DRL). 结果显示了被施用活性的变化,特别是心脏和骨成像中的更高剂量,需要对协议进行优化审查.
科学领域:
- 核医学是一种核医学.
- 放射学 放射学是一门学科.
- 医疗成像医学成像
背景情况:
- 诊断参考水平 (DRL) 是核医学中管理活动 (MBq) 的调查水平,由ICRP引入.
- DRL的目的是防止过度辐射暴露,同时保持图像质量,而不是作为剂量限制.
- 沙特食品和药物管理局 (SFDA) 监督国家DRLs (NDRLs),目前的NDRLs仅限于CT,X射线和哺乳镜.
研究的目的:
- 在沙特阿拉伯国王阿卜杜勒阿齐兹大学医院为核医学成像程序建立本地DRL.
- 为未来对核医学成像监管要求的合规做准备.
- 在核医学程序中确保患者安全并保持足够的图像质量.
主要方法:
- 从所有可用的核医学机器收集回顾性数据.
- 对六种常见的核医学成像协议的研究.
- 根据每项协议的50名标准大小患者的数据计算给药活性 (MBq) 的第50百分位数.
主要成果:
- 脏扫描显示,使用的剂量最低 (130 MBq和148 MBq).
- 骨扫描显示了最高的管理活动,达到高达1110MBq.
- 脏,甲状腺和副甲状腺成像的中位数活性与现有的DRL相当.
结论:
- 为该机构成功建立了用于核医学成像的当地DRL.
- 心脏和骨成像剂量高于当地沙特DRL和国际基准 (欧盟,美国),这表明了协议特定的问题.
- 建议修改协议以优化管理活动,与监管期望和患者安全目标保持一致.

Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...

MRI
MRI uses magnetic fields and radiofrequency signals to distinguish between normal and abnormal tissues. This technology provides a more detailed diagnostic image than CT scans, enabling it to characterize pulmonary nodules, stage bronchogenic carcinoma, and evaluate inflammatory activity in...
