背景情况:
- 常规的24小时头部CT扫描是急性中风后的标准血栓溶解/血栓切除术,即使对于稳定的患者.
- 预测CT结果可以优化成像和患者管理.
- 这项研究旨在确定临床相关的24小时CT发现的预测因素.
研究的目的:
- 在急性缺血性中风患者中开发和验证临床相关的24小时头部CT异常的预测得分.
- 确定影响管理的重要CT发现的独立预测因素.

Imaging Studies for Cardiovascular System V: CT

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...

Imaging Studies for Cardiovascular System VI: Calcium -Scoring CT

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...
