Outline of Final Research Achievements

In this study, we developed a method to estimate Coronary Flow Reserve (FFR), which is one of index of cardiac function using dynamic myocardial CT images. We used images acquired from myocardial perfusion study. We estimated the FFR value from shape and time-dependent change of the CT number on coronary region. We evaluated accuracy of our developed method using coronary model phantom made from 3D printing system. In results of the evaluation, we confirmed that the FFR value was dropped after simulated stenosis region. In addition, we found that the FFR value is dropped after normal branching.
