The pooled performance of the radiomics model demonstrated a sensitivity of 0.79, specificity of 0.85, PLR of 4.6, NLR of 0.30, DOR of 19.21, and AUC of 0.88. Pooled sensitivity exhibited substantial heterogeneity (I²=51.4%), while heterogeneity for other estimates was minimal. Studies using WHO/ISUP tumor grading system showed higher pooled sensitivity compared to those using Fuhrman grading system (Sensitivity: 0.81 vs 0.71, p=0.03, AUC: 0.88 vs. 0.82, p<0.001). Combined models performed comparably to radiomics-only models (AUC: 0.87 vs. 0.85, p=0.1). Nephrographic phase (AUC: 0.67) showed inferior performance compared to corticomedullary phase (AUC: 0.82) and non-contrast images (AUC: 0.83). No considerable publication bias was observed (p=0.73).</p><p><strong>Conclusion: </strong>CT-based radiomics models have demonstrated promise as non-invasive tools for grading ccRCC and may serve as valuable adjuncts in clinical practice.</p>","PeriodicalId":50928,"journal":{"name":"Academic Radiology","volume":" ","pages":""},"PeriodicalIF":3.8,"publicationDate":"2025-06-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144318631","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
