Purpose This study aims to investigate whether non-contrast computed tomography radiomics can effectively reflect split renal function and to develop a radiomics model for its assessment. Materials and methods This retrospective study included kidneys from the study center and split them into training (70%) and testing (30%) sets. Renal dynamic imaging was used as the reference standard for measuring split renal function. Based on chronic kidney disease staging, kidneys were categorized into three groups according to glomerular filtration rate: > 45 ml/min/1.73 m 2 , 30–45 ml/min/1.73 m 2 , and < 30 ml/min/1.73 m 2 .Features were selected based on feature importance ranking from a tree model, and a random forest radiomics model was built. Results A total of 543 kidneys were included, with 381 in the training set and 162 in the testing set. In the training set, 16 features identified as most important for distinguishing between the groups were ultimately included to develop the random forest model. The model demonstrated good discriminatory ability in the testing set. The AUC for the > 45 ml/min/1.73 m 2 , 30–45 ml/min/1.73 m 2 , and < 30 ml/min/1.73 m 2 categories were 0.859 (95% CI 0.804–0.910), 0.679 (95% CI 0.589–0.760), and 0.901 (95% CI 0.848–0.946), respectively. The calibration curves for the kidneys in each group closely align with the diagonal, with Hosmer–Lemeshow test P -values of 0.124, 0.241, and 0.199 for the three groups, respectively (all P > 0.05). The decision curve analysis confirmed the radiomics model's clinical utility, demonstrating significantly higher net benefit than both treat-all and treat-none strategies at clinically relevant probability thresholds: 1–69% and 71–75% for the > 45 ml/min/1.73 m 2 group, 15-d50% for the 30–45 ml/min/1.73 m 2 group, and 0–99% for the < 30 ml/min/1.73 m 2 group. Conclusion Non-contrast computed tomography radiomics can effectively reflect split renal function information, and the model developed based on it can accurately assess split renal function, holding great potential for clinical application.
