Scans were performed in UHR mode at 100 kVp with two different matrix sizes (512\u00d7512 and 1024x1024) and reconstructed at slice thicknesses of 1.5 and 0.2 mm. Image noise, subjective image quality, and ILD changes (ground glass opacities and reticulations) were evaluated on a 5-point Likert-scale by two independent readers.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Results<\/jats:title>\n                  <jats:p>Interreader agreement for subjective image quality ranged from fair to almost perfect (Krippendorff-Alpha: 0.258-0.862). Overall image quality was highest for 1.5 mm\/1024 matrix images [(reader 1: 4(4.4), reader 2: 5(4.5)]. Image sharpness was rated significantly better in 0.2 mm images (P\u2009&amp;lt;\u2009.001). Regarding ILD changes, 0.2 mm slice thickness outperformed 1.5\u2009mm slice thickness significantly (P\u2009&amp;lt;\u2009.001), while there was no significant difference between the two matrix sizes. A 1024-matrix size demonstrated superiority in evaluating coarse reticulations compared to 512-matrix size.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Conclusion<\/jats:title>\n                  <jats:p>UHR mode with a 0.2 mm slice thickness showed enhanced image sharpness and improved visibility of ILD changes compared to standard reconstructions.
