Application value of multiphase contrast-enhanced computed tomography radiomics in preoperative evaluation of peritoneal metastasis in gastric cancer

Key Points

• The multiphase combined model predicts peritoneal metastasis with higher accuracy than single-phase models.
• Diagnostic performance was significantly better, underscoring the value of this new approach.
• Assessment used multiphase contrast-enhanced CT radiomics to gauge effectiveness in prediction.
• This method may enable more individualized preoperative evaluations for gastric cancer patients.
