The evaluation involved quantitative and qualitative analyses of parameters such as SD, SNR, and CNR, as well as a qualitative assessment by two radiology consultants. The outcomes were compared, and the effective dose was calculated and compared with both quantitative and qualitative assessments of image quality.\n                  <\/jats:p>\n                  <jats:p>\n                    <jats:bold>Results:<\/jats:bold>\n                    ROC curve analysis revealed significant differences in CT image quality, with high to moderate specificity and sensitivity across all the quantitative parameters. However, multivariate examination revealed decreasing importance levels, except for CNR (\n                    <jats:italic>B<\/jats:italic>\n                    , 0.203;\n                    <jats:italic>p<\/jats:italic>\n                    = 0.001) and SD BG (\n                    <jats:italic>B<\/jats:italic>\n                    , 0.330;\n                    <jats:italic>p<\/jats:italic>\n                    = 0.002), which increased in\n                    <jats:italic>B<\/jats:italic>\n                    .
