Five sets of images were reconstructed with FBP, ASIR\u2010V at 50% blending level (AR50), and DLIR at low (DLRL), medium (DLRM), and high (DLRH) strength levels. A total of 837 radiomic features were extracted from the pancreatic parenchyma volume to generate five corresponding datasets. Radiomics models for stratifying AP severity were built on four machine learning algorithms, trained on three DLIR datasets (source datasets) and tested on AR50 and FBP datasets (target datasets). The source and target datasets were then swapped for reverse evaluation. Model transferability across datasets was assessed by comparing performance differences between source and target datasets, with area under the receiver operating characteristic curve (AUC) as the primary metric.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>We identified a fundamental asymmetry in model transferability. Models trained on conventional reconstructions (AR50, FBP) demonstrated robust transfer performance to all DLIR datasets, with AUC values in target datasets generally exceeding those in source datasets. In contrast, only models trained on the DLRL dataset exhibited non\u2010inferior transferability when transferred to both AR50 and FBP datasets, with target AUCs being comparable to or higher than those in source datasets.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>The transferability of radiomics models across CT reconstruction algorithms is asymmetric.
