Pre-operative assessment for planned non-coronary cardiac surgeries including valvular heart disease, congenital heart disease, and pericardial disease, in lieu of cardiac catheterization as the initial imaging study, in persons with low or intermediate pretest risk of obstructive CAD; Detection and delin...
1. 基于常规胸部CT平扫的冠状动脉钙化(coronary artery calcium,CAC)评估适应证:适用于所有肺癌筛查患者和40岁以上未确定冠心病的患者。 2.心电门控冠状动脉钙化积分(coronary artery calcium score,CACS)CT检查适应证:(1)10年动脉粥样硬化性心血管病...
The role of computed tomography in cardiovascular risk stratification is well established by means of coronary calcium score (CACS). This role is, as said, well established in asymptomatic individuals,1,2 but is more controversial in symptomatic patients; in fact, it has been more difficult to ...
The coronary calcium score is the new standard for assessing cardiac risk. It is performed with a computed tomography (CT) scanner and special software to determine if the coronary arteries are blocked or narrowed by the buildup of plaque—an indicator for atherosclerosis or coronary artery disease...
arteries before symptoms of heart disease become apparent, so a cardiac calcium score can be used for early detection of coronary artery disease or other heart disease risk factors. If calcium is detected in the arteries, then atherosclerosis (narrowing and stiffening of the arteries) has already ...
Optional decision feedback provides insight in the regions that contributed to the calcium score. Experiments were performed using 903 cardiac CT and 1,687 chest CT scans. The method predicted calcium scores in less than 0.3 s. Intra-class correlation coefficient between predicted and manual calcium...
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...
Validation Using Multiple Cardiac CT and Chest CT Protocols CT中的深度学习用于自动钙评分:使用多个心脏CT和胸部CT协议的验证 Background 背景 Although several deep learning (DL) calcium scoring methods have achieved excellent performance for specific CT pro tocols, their performance in a range of CT ex...
