Objectives:To evaluate the clinical value of multi-slice spiral CT angiography(MSCTA)in the preoperative assessment ofvascular involvement and resectability of pancreatic carcinoma.Methods:Forty-eight cases of pancreatic carcinoma confirmedby surgical pathology were retrospectively analyzed.The state of peripancreatic vessels encroached by pancreatic carcinoma and the resectability were compared between MSCTA and routine axial images;16-slice spiral CT and dual Source CT.Results:For the assessment of resectability and peripancreatic vessel invaded by pancreatic carcinoma

dual source CT was better than 16-slice spiral CT;MSCT angiography was better than routine axial images.Conclusion:MSCT angiography technique can well display the delicate relation between tumor and vessels from different directions

and can delineate the vascular involvement of pancreatic carcinoma with high accuracy.It provides valuable information in the preoperative assessment of pancreatic carcinoma.
