Thin-slice images (0.5\u00a0mm thickness) were reconstructed using SR-DLR, DLR, and HIR. Objective image noise and contrast-to-noise ratio (CNR) for liver parenchyma relative to muscle were assessed. Two radiologists independently graded image quality using a 5-point rating scale for image noise, sharpness, artifact\/blur, and overall image quality. They also graded the visibility of small vessels, main pancreatic duct, ureters, adrenal glands, and right adrenal vein on a 5-point scale.<\/jats:p>\n            <\/jats:sec><jats:sec>\n              <jats:title>Results<\/jats:title>\n              <jats:p>SR-DLR yielded significantly lower objective image noise and higher CNR than DLR and HIR (<jats:italic>P<\/jats:italic>\u2009&lt;\u2009.001).
