Core Tip
Core Tip: Radiomics based on multiphase contrast-enhanced computed tomography offers a promising non-invasive approach for the preoperative assessment of peritoneal metastasis in gastric cancer. By quantitatively capturing tumor heterogeneity beyond visual interpretation, multiphase radiomics models – particularly when integrated with clinical variables – demonstrate improved predictive performance compared with conventional imaging alone. However, heterogeneity in imaging protocols, feature extraction strategies, and model validation remains a major barrier to clinical translation. Standardization and prospective validation are essential before routine clinical implementation.
