这项研究发现,虽然Omicron变异性肺炎影响的是年长,病情更严重的患者,但其CT扫描特征与Delta变异性肺炎相似,Omicron病例中单边肺部感染更为常见.
科学领域:
- 放射学 放射学是一门学科.
- 传染性疾病 传染性疾病
- 肺部病理学 肺部病理学
背景情况:
- 计算机断层扫描 (CT) 对于诊断SARS-CoV-2肺炎至关重要.
- 在德尔塔和Omicron变种之间存在不同的临床特征.
- 变体之间的氧气依赖性肺炎的放射性差异还没有得到充分研究.
研究的目的:
- 比较三角形与Omicron SARS-CoV-2肺炎的放射性和临床特征.
- 专注于需要氧气的住院患者.
- 调查CT发现的差异.
主要方法:
- 回顾性单中心研究 (2021年10月至2022年2月).
- 包括有依赖氧气的SARS-CoV-2肺炎的患者.
- 临床和放射学数据的比较;CT扫描由盲人专家审查.
主要成果:
- 135名德尔塔病毒患者与48名欧米克朗病毒患者.
- 奥米克朗病毒患者年龄较大,免疫力较弱,接种疫苗较多.
- 两者共同的地板玻璃不透明;肺部参与或损伤类型没有显著差异.
- 在Omicron中单侧肺部感染更频繁 (8.3%对0.74%).
结论:
- 奥米克伦肺炎影响的是年龄较大,并发症较多的患者.
- 临床和放射性特征在很大程度上与德尔塔型肺炎相似.
- 单边肺部感染是Omicron肺炎的一个特征.

Phase Contrast and Differential Interference Contrast Microscopy
In-phase-contrast microscopes, interference between light directly passing through a cell and light refracted by cellular components is used to create high-contrast, high-resolution images without staining. It is the oldest and simplest type of microscope that creates an image by altering the wavelengths of light rays passing through the specimen. Altered wavelength paths are created using an annular stop in the condenser. The annular stop produces a hollow cone of...

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...
