增加COVID-19的CT扫描增加了癌症的担忧. 这项研究量化了辐射诱导的癌症风险,发现女性的风险更高,并建议在存在替代方案时限制CT使用.
科学领域:
- 放射学 放射学是一门学科.
- 在瘤学瘤学.
- 公共卫生 公共卫生
背景情况:
- 随着COVID-19大流行,计算机断层扫描 (CT) 扫描用于诊断和监测的使用大幅增加.
- 这一激增引发了人们对潜在的长期健康影响的担忧,特别是辐射诱导的癌症风险.
- 量化这种风险对于明智的医疗保健政策和患者安全至关重要.
研究的目的:
- 评估和量化与用于COVID-19检测的CT扫描相关的潜在癌症风险.
- 评估患者人口统计,CT扫描结果和辐射剂量之间的关系.
- 在传染病管理的背景下,为医疗保健策略提供有关CT扫描使用的信息.
主要方法:
- 一项涉及561名患者的横截面研究,在伊玛目侯赛因医院转诊接受CT扫描.
- CT扫描报告根据放射科医生的解释进行了分类 (正常,异常,潜在异常).
- 用BEIR VII模型来估计辐射诱导癌症的风险.
主要成果:
- 平均有效辐射剂量为1.89 ± 0.21 mSv,女性接受的剂量略高 (2.05 ± 0.29 mSv) 比男性 (1.76 ± 0.11 mSv).
- 所有癌症类型的平均估计终身可归因风险 (LAR) 为每10万患者10.30±6.03例.
- 在CT扫描异常或潜在异常的患者中观察到更高的风险,特别是女性的肺癌平均风险较高 (9.73 ± 3.27 / 100,000),与男性 (3.84 ± 1.19 / 100,000) 相比.
结论:
- 对COVID-19的CT扫描的使用增加为长期癌症发病率带来了显著的潜力.
- 医疗保健政策必须为这种潜在的增长做好准备,强调需要明智地利用CT扫描.
- 应该保留CT扫描在实验室检测不确或临床症状严重的情况下,平衡诊断需求与辐射风险.

Biological Effects of Radiation
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...

Magnetic Resonance Imaging (MRI) and Ventilation Perfusion Scans are two radiological investigations that offer detailed diagnostic images of the body, particularly lung structures.
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...
