CORONARY CT ANGIOGRAPHY: CURRENT & EVOLVING APPLICATIONS

Abstract

Developments in computed tomography (CT) technology since the early 1980s have led to the emergence of non-invasive coronary CT angiography (CCTA). The introduction of electron beam CT (EBCT) permitted the detection of coronary calcification, opening up the door for CT-based cardiovascular imaging.Invasive coronary angiography (l CA) is widely considered a reference standard for the diagnosis of coronary artery disease (CAD) despite the limitations of a "Iuminogram." This procedure is routinely performed in cardiac catheterization laboratories and is generaIly safe.
