Quantifying coronary artery calcification from a contrast-enhanced cardiac computed tomography angiography study.
AIMS We sought to quantify coronary artery calcium (CAC) using a single contrast-enhanced cardiac computed tomography angiography (CCTA) study. CCTA has been successfully used for the assessment of coronary artery stenoses, whereas non-contrast ECG-gated computed tomography (Standard-CAC) is commonly performed to quantify CAC. Thus each scan individually contributes to the total radiation dose....
متن کاملApplication of 64-slice spiral computed tomography angiography in a follow-up evaluation after coronary stent implantation: A Chinese clinical study
Background: This study assessed the application value of 64-slice spiral computed tomography angiography (CTA) in a follow-up evaluation of patients receiving coronary stent implantation. Materials and Methods: A total of 468 patients who underwent percutaneous coronary intervention (PCI) at our hospital between January 2013 and October 2016 were selected for this study. Coronary angiography an...
متن کاملHow to Utilize Coronary Computed Tomography Angiography in the Treatment of Coronary Artery Disease.
Coronary computed tomography angiography (CCTA) has high negative predictive power for detecting coronary artery disease. However CCTA is limited by moderate positive predictive power in the detection of myocardial ischemia. This is not unexpected because the diameter of a stenosis is a poor indicator of myocardial ischemia and discrepancy between the severity of stenosis and noninvasive tests ...
متن کاملCardiac CT Improves Outcomes in Stable Coronary Heart Disease: Results of Recent Clinical Trials
PURPOSE OF REVIEW The purpose of this study was to review the recent randomised controlled trials of coronary computed tomography angiography (CCTA) for patients with stable coronary artery disease. RECENT FINDINGS The initial results and subsequent papers from the SCOT-HEART (Scottish COmputed Tomography of the HEART) and PROMISE (PROspective Multicentre Imaging Study for Evaluation of chest...
متن کاملEvaluation of myocardial ischemia in coronary artery disease with cardiac MR perfusion method: comparison with the results of catheter or CT angiography.
AIM To evaluate the efficacy of the Cardiac Magnetic Resonance Perfusion (CMRP) method in detection of Coronary Artery Disease (CAD) by comparing CMRP findings with the results of Coronary Computed Tomography Angiography (CCTA) or Catheter Coronary Angiography (CCA). METHODS Thirty one patients in whom CMRP was performed along with CCTA or CCA within a month after CMRP between December 2009 a...
متن کاملCoronary computed tomography angiography---a promising imaging modality in diagnosing coronary artery disease.
BACKGROUND Traditionally, information on coronary artery lesions is obtained from invasive coronary angiography (CAG). The clinical applicability and diagnostic performance of the newly developed 64-slice multislice computed tomography (MSCT) scanner in coronary angiographic evaluation is not well evaluated. METHODS Coronary computed tomography angiography (CCTA) was performed in 345 patients...
