Outline of Final Research Achievements

Cardiac CT has emerged as a useful diagnostic imaging method for the non-invasive and accurate evaluation of coronary artery disease. Cardiac CT imaging of low-radiation doses with IR technique have some advantage for the evaluation, but has not been fully investigated. The purposes of our study was to assess the image quality at cardiac CT. Low-dose cardiac CT with Iterative Reconstruction technique method has potentials to provide noise-free image and reduction of radiation exposure, reduction of contrast agent volume, and resulting in improvement of diagnostic performance.
