Abstract
Coronary Artery Calcium (CAC) score is a widely used indicator to determine disease severity and predict the risk of severe cardiac events. However, radiation dose associated with coronary CT scanning for CAC scoring raises concerns, especially for asymptomatic patients. Iterative Reconstruction (IR) technique represents a recently developed image processing approach for reduction of image noise and radiation dose, while improving diagnostic image quality. Despite these advantages over conventional filtered back projection technique, effects of IR techniques on CAC scores remain unclear. This review article aims to provide an overview of clinical applications of IR techniques in coronary CT angiography with a focus on the effects of different IR techniques on CAC score assessment.
Highlights
Coronary Artery Calcium (CAC) scoring is considered a reliable, noninvasive technique for determining coronary plaque burden, risk stratification and reclassification of risk of coronary artery disease.[1]
The rationale behind CAC scoring is that coronary calcification represents atherosclerotic changes in the coronary arterial wall, measurement of the amount of calcium is usually performed to estimate the amount of coronary atherosclerosis and the risk of coronary artery disease (CAD).[5]
This review provides an overview of the clinical applications of iterative reconstruction (IR) in coronary CT angiography (CTA) with regard to its effects on CAC score, with a focus on how IR techniques affect CAC scoring and patient stratification
