Technical innovation is rapidly improving the clinical utility of cardiac computed tomography (CT) and will increasingly address current technical limitations, especially the association of this test with relatively high levels of radiation. Guidelines for appropriate indications are in place and are evolving, with an increasing evidence base to ensure the appropriate use of this modality. New ...

PURPOSE The purpose of this systematic review was to assess the accuracy of 64-slice CT coronary angiography for the diagnosis of coronary artery disease. METHODS We attempted to identify all published trials in all languages that used 64-slice CT to diagnose coronary artery disease. Results of 64-slice CT coronary angiography were compared with invasive coronary angiography or intravascular ...

PURPOSE First, to assess the feasibility of a protocol involving stress-induced perfusion evaluated at computed tomography (CT) combined with cardiac CT angiography in a single examination and second, to assess the incremental value of perfusion imaging over cardiac CT angiography in a dual-source technique for the detection of obstructive coronary artery disease (CAD) in a high-risk population...

A 64-slice computed tomography (CT)—coronary angio-graphy depicted a saccular aneurysm of the left coronary artery located at the bifurcation of the left main into the left anterior descending artery and the left circumflex artery (Fig. 1A). Coronary angiography confirmed the diagnosis (Fig. 1B). The LAD and CX themselves originated directly from the neck of the aneurysm (Fig. 2A and B). Fig. 1...

BACKGROUND Rheumatoid arthritis (RA) is a condition associated with accelerated progression of atherosclerosis in affected individuals. Myocardial assessment using exercise testing in such patients, however, is often difficult to perform. Our objective was to determine the factors associated with severe coronary stenosis using computed tomography (CT) angiography of the coronary arteries in asy...

Background: A single coronary artery (SCA) is a rare anomaly encountered using conventional angiography. right (RCA) originating from left anterior descending (LAD) subtype of SCA. Only few cases are described in published literature. Case presentation: We this 55-year-old male who presented with angina pectoris. The anomalous RCA was suspected by angiogram and confirmed computed tomography (CT...

Diseases of coronary system and heart are the main reason of deaths in highly civilized population. Then the appropriate diagnostic methods and treating of early disorders are very important for a population health care. As the imaging techniques play a great role in good diagnosis they are intensively used and developed. Among the most commonly used methods is coronary angiography, which invol...

Background—Computed tomography (CT) is increasingly used to detect coronary artery disease, but the evaluation of stenoses is often uncertain. Perfusion imaging has an established role in detecting ischemia and guiding therapy. Hybrid positron emission tomography (PET)/CT allows combination angiography and perfusion imaging in short, quantitative, low-radiation-dose protocols. Methods and Resul...

Anomalous coronary artery presenting with acute syndrome is relatively rare. Achilles heel of percutaneous intervention in a such patient difficult cannulation the culprit artery. Coronary CT angiography provides detailed information about origin and course anomalous A few additional like exit angle orifice configuration provided exclusively by helps appropriate hardware selection for angiograp...
