Outline of Final Research Achievements

We made a hollow-fiber phantom for computed tomography perfusion that has the theoretical absolute values of perfusion indices. We investigated quantitative effect of tube current, scan interval, and perfusion analysis algorithm. We reported our result in domestic and international scientific meeting such as European Congress of Radiology, and we published some articles in journals such as Japanese Journal of Radiology. Our fruits were used to optimizing our scan protocols and to reduce radiation dose on patients while maintaining quantitative accuracy. We are continuing reporting our achievement.
