From: Image quality assessment of pediatric chest and abdomen CT by deep learning reconstruction
Abdomen CT images with contrast enhancement in a 15-year-old boy who had abdominal pain with a BMI of 19.9 kg/m2. a–d Axial contrast-enhanced CT images of the same anatomical location show image quality comparison between a standard 50% adaptive statistical iterative reconstruction-V (50% ASIR-V), b 100% ASIR-V, c medium-strength deep learning image reconstruction (DLR-M), and d high-strength deep learning image reconstruction (DLR-H). Contrast to noise ratio (CNR) in the liver was 2.18 in 50% ASIR-V, 2.84 in 100% ASIR-V, 3.03 in DLR-M, 3.88 in DLR-H
