Dual source CT: State of the art in the depiction of coronary arteries anatomy, anatomical variants and myocardial segments

Cardiovascular disease is the leading cause of death in adults in western countries. Coronary angiography remains die gold standard for the diagnosis of coronary artery disease, a procedure that carries risks. Nowadays, a significant number of the coronary angiographies performed every year are only diagnostic. Multidetector computed tomography (MDCT) allows non-invasive evaluation of coronary arteries. It is a continuously developing technique, and actually the top technology is represented by Dual Source CT. This scanner of new conception permits an improvement in image quality, and visualization of distal vessels and small collateral branches. The aim of our work is to illustrate the actual state of the art in non-invasive coronary arteries evaluation represented by Dual Source CT, presenting images of coronary arteries normal anatomy, anatomical variants and myocardial segment.
