Core Tip	Multiphase contrast-enhanced CT radiomics enables non-invasive preoperative prediction of peritoneal metastasis in gastric cancer. In a 200-patient cohort, a combined arterial–venous–delayed model (logistic regression within a leakage-free pipeline) outperformed single-phase models, achieving AUC 0.876 with good calibration and decision-curve net benefit. The approach may help triage candidates for staging laparoscopy, reduce unnecessary exploratory procedures, and support individualized treatment planning. Reporting follows IBSI/TRIPOD-AI, with feature robustness, cross-validation, and external temporal testing recommended for future multicenter deployment.
