Diagnostic Accuracy of Computed Tomography (CT) Coronary Angiography Compared to Invasive Coronary Angiography for Detecting Coronary Artery Disease: A Systematic Review.

Coronary artery disease (CAD) is a significant cause of morbidity and mortality worldwide, and the prevalence is continually rising. Invasive coronary angiography (ICA) has been considered the gold standard in CAD diagnosis as it offers precise information about the presence and severity of coronary artery blockages. However, computed tomography coronary angiography (CTCA) has emerged as a preferred noninvasive imaging technique from the viewpoint of patient risk because it provides high-resolution coronary images.
