在CT扫描中患者诱导的文物显著减少COVID-19评估的诊断协议. 运动文物对COVID-19报告和数据系统 (CO-RADS) 和CT严重性得分 (CT-SS) 的可靠性影响最大.
科学领域:
- 放射学 放射学是指放射学
- 医疗成像医学成像
- 传染病诊断 传染病诊断 传染病诊断
背景情况:
- 计算机断层扫描 (CT) 对于诊断COVID-19至关重要.
- 患者诱导的文物可能会损害CT图像质量.
- 像CO-RADS和CT-SS这样的标准化评分系统旨在提高诊断的一致性.
研究的目的:
- 评估患者诱导的文物如何影响COVID-19报告和数据系统 (CO-RADS) 和CT严重性得分 (CT-SS) 的诊断性能.
主要方法:
- 549名COVID-19患者的胸部CT扫描的回顾性分析.
- 放射科医生对CO-RADS和CT-SS分类的扫描进行了评估.
- 确定的文物包括金属,不完整的投影,运动和不足的灵感.
- 使用Fleiss kappa.测量了读者之间的一致性.
主要成果:
- 对CO-RADS的最高读者间一致性是在没有人造物 (κ=0.924) 的患者中.
- 运动文物显示CO-RADS (κ=0.613) 和CT-SS (κ=0.374) 的协议最低.
- 灵感不足特别影响了CO-RADS 1和2的协议.
结论:
- CT文物降低图像质量,导致CO-RADS和CT-SS在COVID-19患者中的互读器协议减少.
- 技术人员可以通过仔细的患者定位,指令和优化扫描参数来减轻人工制品.

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...

Imaging Studies for Cardiovascular System III: X-Ray
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...
