| Summary: | Assessment of myocardial ischemia in patients with stable angina is important in deciding
whether to treat coronary artery disease and in predicting clinical outcome. The fractional flow
reserve is a standard reference for the diagnosis of myocardial ischemia, but this procedure has
limitations because of its invasiveness. Coronary computed tomography angiography (CCTA) is
now an established tool in the anatomic diagnosis of coronary artery disease; however, there
are limits to the diagnosis of hemodynamically important stenosis that causes myocardial ischemia.
In order to address this problem, studies using quantification of coronary atherosclerotic
plaques, myocardial perfusion, and noninvasive calculation of fractional flow reserve based on
CCTA have been actively conducted and recognized for their diagnostic value. In this review,
several imaging techniques of CCTA used to assess myocardial ischemia are described. |
