Objectives: High-pitch imaging in computed tomography (CT) reduces scan time and radiation dose at the expense of increased noise. Recent advances in iterative reconstruction techniques allow for noise reduction without a significant increase in processing time, by using Sinogram-Affirmed Iterative Reconstruction (SAFIRE). We evaluated the combined effects of high-pitch imaging with SAFIRE in CT of the thorax and abdomen on image quality, diagnostic confidence, and radiation dose in children.
