- Non-invasive prediction of myocardial ischemia has been important issue to determine whether revascularization therapy performs or not in patient with stable coronary artery disease. - Quantitative coronary CT angiography, myocardial CT perfusion, and CT-based fractional flow reserve (FFR) are emerging  methods for evaluation of myocardial ischemia. - In this exhibition, we will present current status, analysis methods, and pitfalls of each technique

1. Importance of ischemia-guided coronary revascularization     A. Brief review of recent clinical studies 2. Limitation of conventional visual analysis of coronary CTA 3. Current status of CT-based myocardial ischemia prediction     A. Quantitative coronary CTA          i.  Plaque quantification     B. CT myocardial perfusion         i. Review of clinical studies     C. CT-FFR         i. Review of clinical studies including DISCOVER-FLOW, DeFACTO, and NXT trials 4. How to perform CT-based myocardial ischemia prediction     A. Quantitative angiography        i. Aggregated plaque volume     B. CT myocardial perfusion        i. Static vs. dynamic perfusion protocol       ii. Imaging interpretation     C. CT-FFR        i. Generation of 3D model of coronary trees       ii. Calculation of CT-FFR using computation fluid dynamics 5. Typical cases and pitfall of each techniques
