CT venous-phase radiomics for preoperative differentiation of early and advanced gastric cancer: construction, comparison, and validation of machine-learning models
To construct various radiomics models based on CT venous-phase images for the quantitative assessment of gastric cancer (GC) invasion depth into the gastric wall, and to compare the diagnostic performance of different machine-learning models in distinguishing early (T1–T2 stage) from advanced (T3–T4 stage) GC, ai...
