1. We will review a basic theory of CT-FFR focused on three dimensional modeling of coronary three and computational fluid dynamics.  2. We will provide various cases of CT-FFR with correation with CT angiography, invasive angiography, and FFR

1. Introduction of FFR and CT-based FFR 2. Procedures for CT-based FFR measurement  A. Image acquisition from cardiac computed tomography angiography (CCTA)  - Tips for image quality management in CT-based FFR  B. Morphology reconstruction of coronary arterial trees  - Threshold- and gradient-based segmentations methods  C. Modeling for vessel walls  - Elasticity  D. Modeling for fluidic properties of blood  - Viscosity and density  E. Boundary conditions  - Bifurcation laws  - Inflow: Myocardial mass, heart rate and hyperemia  - Outflow: Wind-kessel model, lumped parameter model and etc. 3. Prospect for CT-based FFR measurement - Current outcomes, technical obstacles and potentials - Roles of radiology in improvement of CT-based FFR 4. Clinical cases review
