Coronary CT Angiography in the Quantitative Assessment of Coronary Plaques
Coronary computed tomography angiography (CCTA) has been recently evaluated for its ability to assess coronary plaque characteristics, including plaque composition. Identification of the relationship between plaque composition by CCTA and patient clinical presentations may provide insight into the pathophysiology of coronary artery plaque, thus assisting identification of vulnerable plaques whi...
متن کاملCoronary CT angiography.
Advances in multidetector CT (MDCT) technology with submillimeter slice collimation and high temporal resolution permit contrast-enhanced imaging of coronary arteries and coronary plaque during a single breath hold. Appropriate patient preparation, detailed technical and technological knowledge with regard to recognition of typical imaging artifacts (such as beam hardening or motion artifacts),...
متن کاملImaging Quality Evaluation of Low Tube Voltage Coronary CT Angiography Using Low Concentration Contrast Medium
PURPOSE To compare the image quality of prospectively ECG-gated low voltage coronary computed tomography angiography (CTA) with an administration of low concentration contrast medium. METHOD AND MATERIALS A total of 101 patients, each with a heart rate below 65 beats per minute (BPM), underwent a prospectively ECG-gated axial scan in CT coronary angiography on a 64-slice CT scanner. All patie...
متن کاملCT coronary angiography vs. invasive coronary angiography in CHD
SCIENTIFIC BACKGROUND Various diagnostic tests including conventional invasive coronary angiography and non-invasive computed tomography (CT) coronary angiography are used in the diagnosis of coronary heart disease (CHD). RESEARCH QUESTIONS The present report aims to evaluate the clinical efficacy, diagnostic accuracy, prognostic value cost-effectiveness as well as the ethical, social and leg...
متن کاملCoronary CT angiography in percutaneous coronary intervention
Technical advances have enabled multidetector CT to become the non-invasive modality of choice for coronary imaging. Recent clinical literature has supported the power of CCTA using 64-slice multidector CT scanners in the detection and ruling out of significant (> 50%) coronary artery disease, with an average negative predictive value of 98% on a per-patient basis [6-8]. With the capability of ...
