A cardiac computerized tomography (CT) scan – which can also be referred to as a coronary CT angiography or CT angiogram – is an imaging test to view the heart and blood vessels. It is a test that carries few risks and is less invasive than alternative procedures such as an angiogram....

Cardiac CTA is also a useful alternative to invasive coronary angiography for pre-operative evaluation of persons undergoing non-coronary cardiac surgery or high-risk non-cardiac surgery, where invasive coronary angiography would otherwise be indicated. Einstein and colleagues (2007) ascertained the lifet...

Direct visualization of the epicardial coronary arteries is currently the reference standard to confirm the presence or focal severity of coronary luminal disease, or both. For more than 50 years1 the coronary angiogram has been used to define epicardial

目前,CT在心血管疾病诊断中的应用主要包括心脏血管钙化积分CCS(coronary calcium score)和心脏CT冠脉造影CCA(coronary CT angiogram)。心脏血管病灶钙化主要分为4大类:0-没有钙化;1-99轻度钙化;100-399中度钙化;大于400属于严重钙化。研究已证明,钙化积分是直接与心脏危险事件及心脏血管的阻塞程度有关[3]。也就是说...

心脏淀粉样变性(Cardiac Amyloidosis,CA)患者的总体CT-ECV值为50. 2%(95% CI 46. 2%-54. 2%),具有显著异质性(I2 = 88. 5%): 在几乎所有研究中,心脏淀粉样变性患者的CT-ECV都远远高于健康患者。 Deux等人的研究(Ref 57)表明: 心脏淀粉样变性的CT-ECV(54.7% ± 9.7%)高于非淀粉样蛋白性心脏肥大患者(...
