背景情况:
- 冠状病毒感染呈现出多样化的胸部CT发现.
- 肺炎是一种常见的并发症,影响患者的治疗结果.
- 了解CT模式及其与疾病严重程度的相关性至关重要.
研究的目的:
- 在冠状病毒感染中对胸部CT模式进行定量分析.
- 为了将CT发现与病毒载量和病理生理状态相关联.
- 为了识别冠状病毒相关肺炎的成像标记物.
主要方法:
- 对171名冠状病毒感染患者进行了回顾性队列研究.
- 胸部CT分析分类肺炎和非肺炎组.
- 在CT特征 (GGO,整合) 和实验室标记 (LYM,CRP,NLR,D-二次体) 之间的相关性分析.
- ROC曲线分析用于LYM的预测值;多重线性回归用于CT模式-生理关系.
主要成果:
- 与非肺炎相比,肺炎组 (74.3%) 的LYM,PaO2/FiO2较低,CRP,NLR,D-二次和整合比率较高.

Imaging Studies for Cardiovascular System III: X-Ray
141
The most common cardiovascular diagnostic test is an X-ray. It produces images of the heart, blood vessels, and adjacent structures.
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...
