Coronary CT Angiography

Journal of the American College of Radiology, 2006
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 ...

Coronary CT Angiography: Applications

Radiologic Clinics of North America, 2009
With the widespread use of coronary CT angiography, new potential clinical indications are constantly being explored. Currently, 64-slice multidetector-row CT and dual-source CT are the benchmark for noninvasive coronary CT angiography; however, new technologies are already on the horizon.

Developments in coronary CT angiography

Current Cardiology Reports, 2008
CT imaging of the coronary arteries by contrast-enhanced CT, termed "coronary CT angiography" or "coronary CTA," has become increasingly stable and robust during the past few years. Several trials have demonstrated rather high diagnostic accuracies in somewhat selected patient groups, and this method can be applied clinically to rule out coronary ...

Coronary In-Stent Restenosis: Assessment with CT Coronary Angiography

Radiology, 2012
To compare accuracy and radiation exposure of a new computed tomographic (CT) scanner with improved spatial resolution (scanner A) with those of a CT scanner with standard spatial resolution (scanner B) for evaluation of coronary in-stent restenosis (ISR) by using invasive coronary angiography (ICA) and intravascular ultrasonography (US) as reference ...

Multislice CT in cardiac and coronary angiography

The British Journal of Radiology, 2004
In the last 2 years, mechanical multidetector-row CT (MDCT) systems with simultaneous acquisition of four slices and a half second scanner rotation time have become widely available. Data acquisition with these scanners allows for considerably faster coverage of the heart volume compared with single slice scanning. This increased scan speed can be used

Prognostic Value of Coronary CT Angiography

Cardiology Clinics, 2012
Coronary computed tomography angiography (CTA) is a highly accurate noninvasive test that is increasingly used in symptomatic patients primarily for the diagnosis of coronary artery disease (CAD). Beyond its proven accuracy, data have now clearly demonstrated the incremental prognostic information available from coronary CTA related to the presence ...

The Prognostic Significance of Coronary CT Angiography

Current Cardiology Reports, 2011
Coronary computed tomography angiography (CTA) is an increasingly utilized, highly accurate noninvasive test for the diagnosis of coronary artery disease. Accumulating data have convincingly demonstrated that the presence, extent, and location of both obstructive and nonobstructive coronary atherosclerosis visualized on coronary CTA conveys powerful ...

CT Coronary Angiography

2006
Non-invasive CT angiography of the coronary arteries is a challenging and rapidly advancing technique. Electron beam tomography initially permitted the non-invasive visualization of coronary arteries and detection of stenoses. Multidetector CT provides very high spatial resolution and allows for excellent visualization of the coronary arteries ...

Coronary vasospasm during CT angiography

Journal of Cardiovascular Computed Tomography, 2014
A 71-year-old man, a heavy smoker, was admitted for evaluation of "chest oppression" after every dinner. Cardiac CT with a beta-blocker showed coronary stenosis in the left circumflex. Although adenosine triphosphate-stress perfusion single-photon emission CT revealed no ischemia, Holter electrocardiography belatedly indicated an ST elevation ...
