Coronary Computed Tomography Angiography (CCTA) of the heart in emergency conditions

Princy Bandla

A coronary computed tomography angiogram uses advanced CT methods, along with intravenous (IV) contrast material (dye), to acquire highresolution, 3D pictures of the moving heart and great vessels. CTA is also known multi-slice computed tomography (MSCT), cardiac CT or cardiac CAT. Throughout CTA, x-rays pass through the body and are picked up by detectors in the scanner, that release 3D images on a computer screen. These images are enabling physicians to determine whether plaque or calcium deposits are present in the artery walls.
