Coronary 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 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 ...
متن کاملconus artery in coronary ct angiography
conclusions in most cases, the conus artery can be visualized in cardiac ct. a description of the conus artery should be a part of the standard clinical coronary ct angiography description. objectives to examine whether it is possible to visualize the conus artery in multi-slice computed tomography (ct). patients and methods in 79 consecutive patients (aged 56 ± 12.9 years; 13 women), 64-slice ...
متن کاملimproved image quality of coronary ct angiography using automatic motion correction
background motion artifacts that degrade image quality of coronary ct angiography (ccta) in patients with high heart rates may be reduced with specific automatic motion correction algorithms (amc). conclusions ccta image quality improves significantly with amc in patients with high heart rates and reduces the proportion of non-diagnostic examinations. results mean heart rate during ccta was 61 ...
