Automated three-dimensional quantification of noncalcified coronary plaque from coronary CT angiography: comparison with intravascular US.
PURPOSE To determine the accuracy of a previously developed automated algorithm (AUTOPLAQ [APQ]) for rapid volumetric quantification of noncalcified and calcified plaque from coronary computed tomographic (CT) angiography in comparison with intravascular ultrasonography (US). MATERIALS AND METHODS This study was approved by the institutional review board and was HIPAA compliant; all patients ...
متن کاملHigh-Risk Plaque Features on Coronary CT Angiography.
CORONARY COMPUTED TOMOGRAPHIC ANGIOGRAPHY (CTA) HAS BECOME AN ACCEPTED TOOL FOR THE evaluation of obstructive coronary artery disease, with high accuracy and proven prognostic implications. Although detailed information regarding plaque characteristics is available in coronary CTA datasets of sufficient quality, clinical decision making utilizing the information offered by computed tomography–b...
متن کاملCoronary plaque quantification and fractional flow reserve by coronary computed tomography angiography identify ischaemia-causing lesions
AIMS Coronary plaque characteristics are associated with ischaemia. Differences in plaque volumes and composition may explain the discordance between coronary stenosis severity and ischaemia. We evaluated the association between coronary stenosis severity, plaque characteristics, coronary computed tomography angiography (CTA)-derived fractional flow reserve (FFRCT), and lesion-specific ischaemi...
متن کاملUnstable coronary plaque and its relation to coronary calcium.
Coronary calcium is intimately associated with coronary atherosclerotic plaque development. The use of electron-beam computed tomography (EBCT) for accurate quantitative measurements has led to an increased interest in understanding the clinical importance of coronary calcium, particularly in terms of the ability to identify unstable coronary plaques that underlie the clinical acute coronary sy...
متن کاملPlaque sealing by coronary angioplasty.
T he concept of plaque sealing by coronary balloon angioplasty has been around for some time. It is based on two principles. First, a coronary stenosis subjected to balloon angioplasty will not progress to a total occlusion later on unless it occludes abruptly during or immediately after the intervention. Even if a restenosis occurs, the smooth inner lining of the intimal proliferation virtuall...
