This study examines the hypothesis that four-dimensional noise reduction (4DNR) with short interval times reduces noise in cardiac computed tomography (CCT) using ˇ°paddingˇ± phases. Furthermore, the capability of reducing the reduction dose in CCT using this post-processing technique was assessed %K Image quality %K Computed tomography %K Radiation dose %K Temporal noise reduction %K Cardiac CT %U https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4756736/
