Computed tomographic assessment of coronary artery disease: state-of-the-art imaging techniques

Radiologic Clinics of North America
Thomas G FlohrFelix G Meinel

Abstract

While coronary computed tomography (CT) angiography and more refined imaging of the coronary anatomy have driven technical innovation in cardiac CT for the last 10 years, there is now an increasing focus on functional applications of cardiac CT, such as evaluation of the myocardial blood supply or assessment of dynamic myocardial perfusion. Novel techniques show promising results. This article focuses on state-of-the-art CT imaging techniques to visualize the coronary anatomy, describes aspects of radiation dose reduction, and briefly touches on recent approaches to obtain functional information from a CT scan of the heart, in particular dual-energy CT.

Atrial Fibrillation

Atrial fibrillation is a common arrhythmia that is associated with substantial morbidity and mortality, particularly due to stroke and thromboembolism. Here is the latest research.

Arrhythmia

Arrhythmias are abnormalities in heart rhythms, which can be either too fast or too slow. They can result from abnormalities of the initiation of an impulse or impulse conduction or a combination of both. Here is the latest research on arrhythmias.
