Images were reconstructed using PIQE (strength level L1 and L2) and AiCE (L1\u2013 the institutional standard). Four blinded radiologists assessed image noise, image contrast, small structure visibility, image sharpness, artifacts, and overall image preference with Likert scales. Reader agreement was assessed with Krippendorff's alpha. Circular regions of interest were placed on five slices on the left and right liver, portal vein, aorta, subcutaneous fat, and bilateral psoas muscles. CT number, noise, signal\u2010to\u2010noise ratios (SNRs), and contrast\u2010to\u2010noise ratios (CNRs) were determined. All significant differences between reconstructions were assessed via the Friedman test with post\u2010hoc Dunn\u2010Sidak corrections.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      Reader agreement was fair ().
