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.
