Abstract：Objective: To investigate the relationship between the size of the lesion, differentiation grade and the diameter of the pancreatic duct and common bile duct by using imaging surface reconstruction in 64-MDCT. Methods: Forty-five patients MDCT imaging with pancreatic ductal adenocarcinoma(confirmed by pathology) were retrospective analyzed from September 23, 2013 to June 17, 2015. The diameter of the main pancreatic duct, the longest diameter of the main pancreatic duct and the diameter of the common bile duct were statistically analyzed. Results: High(7 cases), medium(21) and low(17) differentiated ductal adenocarcinoma were confirmed in this group; and average size of pancreatic head carcinoma was (2.33±0.86) cm. There was no correlation between differentiated grade and its average diameter of common bile duct at upper and posterior duodenal level. There was positive correlation between differentiated grade and average diameter of common bile duct obstruction upstream. There was no correlation among the size of pancreatic head carcinoma with diameter of the neck, body and tail of the main pancreatic duct, and negative correlation between the pancreatic head carcinoma and average diameter of the main pancreatic duct and positive correlation with average diameter of the pancreatic duct obstruction at upstream level. Between poorly and moderately differentiated pancreatic ductal adenocarcinoma, average diameter of the upper main pancreatic duct was statistically significant difference. Upstream bile duct diameter was no statistically significant difference among poorly, moderately and highly differentiation of ductal adenocarcinoma. Conclusion: Differentiation garde of pancreatic head carcinoma was certainly correlated with the average diameter of the main pancreatic duct.
