概括
来自CT的微分流量储备可以准确评估冠状动脉狭窄. 然而,这个案例表明,严重的狭窄可能不会显著改变CT衍生的分流储量,受大分支等因素的影响.
科学领域:
- 心血管成像 - 心血管成像
- 干预心脏病学 干预心脏病学
- 计算流体动力学的流体动力学.
背景情况:
- 来自计算机断层扫描 (CT-FFR) 的分量流量储备是诊断冠状动脉疾病的有价值的非侵入性工具.
- 严重的冠状动脉狭窄通常会导致CT-FFR值在整个病变的显著下降.
- 准确的CT-FFR评估对于指导复血管化决策至关重要.

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...
