Calculation of tumor volume and remnant pancreas volume based on three-dimensional reconstruction of CT images. (A) Three-dimensional image of the pancreas and surrounding organs. The yellow region represents the pancreas, the orange region represents the tumor, the red region represents the duodenum, and the green region represents the bile and pancreatic ducts. The remnant pancreas volume was determined by identifying the entire pancreatic region and subtracting the tumor volume and the volume of the extended pancreatic duct and bile duct. Comparison of (B) remnant pancreas volume and (C) tumor volume between PDAC patients with different glucose tolerance statuses. * p value less than 0.05, *** p value less than 0.001, **** p value less than 0.0001; ns, no significance.
