计算机断层扫描 (CT) 胸部检查在COVID-19大流行期间增加,之后稳定. 由于技术进步和改进的剂量管理,每名患者的辐射暴露减少,在医学成像中建立了新的规范.
科学领域:
- 放射学和医学成像学 医学成像学
- 公共卫生 公共卫生
- 流行病学 流行病学
背景情况:
- COVID-19 流行病显著改变了全球医疗保健提供和诊断成像实践.
- 胸部的计算机断层扫描 (CT) 是一种至关重要的诊断工具,特别是在呼吸系统疾病中.
研究的目的:
- 分析COVID-19大流行之前,期间和之后CT胸部检查和患者辐射暴露的趋势.
- 评估大流行对CT胸部成像利用和辐射剂量测量的影响.
主要方法:
- 来自10家公共医院的24万多次CT胸部检查的回顾性分析.
- 数据收集涵盖了流行病前 (2019年 - 2020年2月),流行病前 (2020年3月 - 2023年4月) 和流行病后 (2023年5月 - 2024年12月) 的时间段.
- 使用商业剂量管理系统和统计分析来比较检查数量和辐射暴露.
主要成果:
- 在大流行期间观察到CT胸部检查的显著增加,在后流行阶段稳定 (p < 0.001).
- 随着时间的推移,每次检查的患者平均辐射暴露量下降,反映了技术进步和更好的剂量管理.
- 一个显著的转变,更专注的CT胸部协议发生在疫情期间.
结论:
- 胸部CT检查显示持续需求,流行病时代的做法成为常态.

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...
Radiological Investigation III: Pulmonary Angiogram and PET Scan
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...

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...
