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...

75572 Computed tomography, heart, with contrast material, for evaluation of cardiac structure and morphology (including 3D image postprocessing, assessment of cardiac function, and evaluation of venous structure, if performed 75573 Computed tomography, heart, with contrast material, for evaluation of card...
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 ...
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...
This study sought to compare computed tomography delayed enhancement (CTDE) against cardiac magnetic resonance (CMR) late gadolinium enhancement (LGE) for detection of ischemic scar and to test the additive value of CTDE as part of a comprehensive multidetector computed tomography (MDCT) stress–rest...
1 Coronary angiography J-CTO score of 0 or 1; 2 Pregnancy or other protection by law; 3 Very frequent irregular cardiac rhythm (arrythmia?/tachycardia?) > 100 beats/min; 4 Concomitant pathologies that introduce additional risks, such as hemodynamic instability, anaemia < 9 g/dl, gastroi...
The tiered cardiac CT protocol included a calcium scan followed by CT angiography if the Agatston calcium score was between 1 and 400. Patients with test-specific contraindications were not excluded from study participation. Sex differences were studied as a prespecified subanalysis. Enrolled women ...
Cardiac CT > All SubspecialtiesLatest News Study Shows Merits of CTA-Derived Quantitative Flow Ratio in Predicting MACE By Jeff Hall December 12th 2024 For patients with suspected or known coronary artery disease (CAD) without percutaneous coronary intervention (PCI), researchers found that those with...
