intensity mapping, ventricular function, wall shear stress.
The purpose of quantitative evaluation of cardiac images is to acquire more objective, accurate, and delicate
numeric data than from the results of qualitative observation. By quantitative analysis, the prediction of cardiovascular
risk and the depiction of subtle changes have become more reliable. Until cardiac computed tomography (CT) and magnetic
resonance imaging (MRI) were introduced 10 years ago, echocardiography had been traditionally used for cardiac
morphology imaging. Based on technical advancements, cardiovascular CT and MRI started to be used for quantitative
evaluation of cardiovascular structures. In this article, quantitative evaluation techniques in cardiovascular imaging will be
discussed with an emphasis on CT and MRI.
