ABSTRACT

The study of atherosclerotic disease in coronary arteries is fundamental since it is the first cause of death in the Western hemisphere. The gold standard for its diagnosis is invasive angiography, but it contributes to an increase in costs for this group of patients. Nowadays fourth generation computed tomography (CT) equipments can construct acquisition data of up to 256 images in only 400 milliseconds (ms), which is 900 to 1000 times faster than first generation apparatus. CT multidetector (CTMD) is the noninvasive choice diagnosis method for a vascular evaluation of the thorax. Its role in the study of the heart was limited, but today it is possible to obtain three-dimensional heart and whole body images in only seconds. CTMD is a fast, low-cost, noninvasive method that generates cardiac and extra cardiac images without adjacent structure interference. The higher temporal resolution due to an increase of the gantry’s rotation and new reconstruction algorithms, as well as its higher spatial resolution and elevated time acquisition due to the presence of more detectors, havepermitted CTMD to give significantly better and precise diagnosis of coronary arteries.
