Coronary CT angiography: current & evolving applications.
Pak Heart J Jan ;43(1):08-15.

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. The EBCT scanner, introduced in 1983, was able to capture a highresolution image despite the motion of a beating heart; however, EBCT lacked adequate spatial resolution to adequately visualize small structures like coronary arteries. Multidetector CT (MDCT) scanners were introduced in the 1990s and provide higher spatial resolution and the capability to perform a diagnostic-quality CCTA using iodinated contrast agents for coronary lumen opacification. Since then, MDCT technology has exploded and now 16 to 64 slice scanners coupled with advanced software packages for image acquisition and reconstruction are widely available.
