概括
在头部CT扫描中发现的超过三分之一的旧中风是患者和医生以前不知道的. 识别这些无声冲击为二次预防提供了至关重要的机会,有可能每年帮助数十万人.
科学领域:
- 神经学 神经学
- 放射学 放射学是一门学科.
- 公共卫生 公共卫生
背景情况:
- 在神经成像上偶然发现以前未知的中风,为二次预防提供了关键的机会.
- 二次预防策略可以将重复中风的风险降低高达80%.
研究的目的:
- 为了确定在急诊室 (ED) 头部CT扫描上发现的以前未知的中风的流行率.
- 为了确定与这些未知的中风相关的患者和成像因素.
主要方法:
- 从7月到2023年12月的三个ED中接受头部CT的成年患者 (年龄≥18) 的回顾性分析.
- 以往已知的或未知的旧的分类.
- 使用单变量和多变量回归以及决策树分析评估相关因素.
主要成果:
- 在21,985个头部CT中,有869个 (4.0%) 显示了旧的中风,其中372个 (43%的旧中风,1.7%的所有CT) 之前是未知的.
- 不知名的中风与年龄较大,单次中风地点,较小的心脏病发作和特定位置 (状囊,小脑) 有关.
结论:
- 在头部CT成像中检测到的超过三分之一的旧中风是未被患者和临床医生识别的.

Calcium-Scoring CT ScanA calcium-scoring CT scan, also known as coronary artery calcium (CAC) scan, detects calcium deposits in the coronary arteries. This test assesses the risk of coronary artery disease (CAD), which can lead to cardiovascular events such as angina, heart failure, and sudden cardiac arrest.A calcium-scoring CT scan is generally recommended for individuals at intermediate risk of CAD without symptoms. It includes:Men aged 40-75 and women aged 50-75: Especially those with a...

Cardiac computed tomography (CT) scanning is an advanced cardiac imaging technique that utilizes CT technology, with or without intravenous (IV) contrast, to produce accurate cross-sectional virtual slices of specific areas of the heart, coronary circulation, and major blood vessels such as the aorta, pulmonary veins, and arteries. The computer processes these slices to generate three-dimensional images. Multidetector CT (MDCT) is a rapid form of CT scanning that captures multiple slices...

Tomography refers to imaging by sections. Computed tomography (CT) is a non-invasive imaging technique that uses computers to analyze several cross-sectional X-rays to reveal minute details about structures in the body.
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...
