Outline of Final Research Achievements

We have built the protocol of dual source CT scan to evaluate the morphological feature of congenital heart defect. Using sinogram-affirmed iterative reconstruction, radiation dose of CT scan and image noise could be reduced. The outcome of our study suggest that dual source CT has the capacity to clearly depict the configurations of ventricles in patients with lower radiation doses. This research subjects were reported in articles (Pediatr Radiol. 2015;45:1472-9、Jpn J Radiol. 2016;34:284-91).
