Outline of Final Research Achievements

In recent years, coronary artery disease in Japan has been increasing, accurate diagnosis and evaluation of therapeutic indication are required. However, it is known that sufficient improvement of patient prognosis can not be obtained by evaluation of therapeutic indication by morphological evaluation such as conventional coronary stenosis ratio. Therefore, the non-invasive and objective method of evaluating ischemia was expected. In this study,we proposed Quantitative Perfusion Ratio (QPR) calculated from the Dynamic CT Perfusion and examined its accuracy.
