Abstract: Objective: peritoneal free cancer cells can negatively impact disease progression and patient outcomes in gastric cancer. This study aimed to investigate the feasibility of using magnetic resonance (MR) golden-Angle Radial Sampling (GRASP) dynamic contrast-enhanced imaging to predict the presence of peritoneal free cancer cells in gastric cancer patients. Methods: All enrolled patients were consecutively divided into analysis and validation groups. Preoperative MRI scans and perfusion were performed in patients with gastric cancer undergoing surgery, and peritoneal lavage specimens were collected for examination. Based on the peritoneal lavage cytology (PLC) results, patients were divided into negative and positive lavage fluid group. The data collected included clinical and magnetic resonance information. A nomogram prediction model was constructed to predict the positive rate of peritoneal lavage fluid, and the validity of the model was verified based on data from the verification group. Results: There was no statistical difference between the proportion of PLC positive cases predicted by GRASP MR and the actual PLC test (χ2=7.26, P=0.95). MR Tumor (T) staging, tumor thickness, and perfusion parameter Tofts-Ketty model volume transfer constant (Ktrans) were independent predictors of positive peritoneal lavage fluid. The nomogram model featured a C-index of 0.785 and 0.742 for the modeling and validation groups, respectively. Conclusion: GRASP MR dynamic contrast-enhanced imaging could effectively predict peritoneal free cancer cells in gastric cancer patients. The nomogram model constructed using these predictors may help clinicians to better predict the risk of peritoneal free cancer cells being present in gastric cancer patients.
