Fig. 3From: 75% radiation dose reduction using deep learning reconstruction on low-dose chest CTA woman received low-dose chest CT for the follow-up evaluation of multiple ground-glass nodules. (A-C) Conventional low-dose chest CT images were reconstructed with iterative reconstruction, and (D-F) the images generated using a quarter dose of radiation were reconstructed with commercial deep-learning software. (A, D) Soft-tissue structures, including the liver, spleen, kidney, and paraspinal muscles, were visualized with a lower noise level in the mediastinal-window setting on both images. (C, F) A ground-glass nodule in the right upper lobe was well visualized with a sharp margin on both images (arrow)Back to article page
