科学领域:
- 肺部病理学 肺部病理学
- 放射学 放射学是一门学科.
- 传染性疾病 传染性疾病
背景情况:
- 虽然COVID-19的诊断依赖于鼻口腔抽样,但评估肺部参与对于患者管理至关重要.
- 肺部超声波 (LUS) 是一种无辐射的,用于肺部疾病的床边成像模式.
- 高分辨率计算机断层扫描 (HRCT) 是评估肺炎程度的黄金标准.
研究的目的:
- 评估肺超声波 (LUS) 作为检测COVID-19患者肺部参与的工具.
- 将LUS与HRCT在评估COVID-19肺炎中的疗效进行比较.
- 探索LUS得分和血液气体参数之间的相关性.
主要方法:
- 一项单中心前性研究招募了131名疑似COVID-19的患者.
- 12个肺部区域使用半定量LUS评分系统进行评估.
- 患者接受了LUS,逆转录聚合酶链反应 (rRT-PCR),血液分析和HRCT.
主要成果:
- LUS得分显示了与pO2,P/F和SpO2的逆相关性,以及与AaDO2的直接相关性 (p < 0.01).
- 与HRCT相比,LUS的灵敏度为81.8%,特异性为55.4%,负预测值 (VPN) 为75%,正预测值 (VPP) 为65%.
- 在COVID-19患者中,LUS确定了肺部参与.
结论:
- 肺超声波 (LUS) 是检测COVID-19患者肺部卷入的一个有价值的工具.
- 在COVID-19中评估肺炎时,LUS是HRCT的有效,无辐射的替代品.
- LUS可以帮助管理COVID-19患者,特别是那些有轻度症状的患者.

Ultrasound I: Abdominal Ultrasonography
Abdominal ultrasonography, commonly known as abdominal ultrasound, is a vital, non-invasive medical imaging technique widely used in healthcare.
Procedure:
This diagnostic tool allows the clinician to visually inspect internal structures within the abdomen, including vital organs such as the liver, gallbladder, pancreas, kidneys, and spleen.
The abdominal ultrasound process begins with applying a special gel to the patient's skin over the abdomen. This gel enhances the...
