This retrospective study was performed to assess CT scan findings of pancratic cancer and its ability to determine resectability. CT scan of 41 patients. who were diagnosed to have pancreatic cancer on histological or clinical base, were reviewed. Most common findings were : focal pancreatic enlargement , diffuse pancreatic enlargement, loss of distinct controur, peripancreatic fat obliteration , bile duct or pancreatic duct dilatation, vascular invasion , lymphmode involvement , direct invasion if adjacent organs and distant metastasis. Resectability was assessed according to generally accepted CT findings such as small pancreatic mass lesion having normal lobulated controur of pancreas, no evidence of vascular invasion, no evidence of lymph node involvement and free of distant metastasis. With the criteria, 5 cases among 41 cases deemend to be resectable. However on operation all cases were found unresectable indicating prediction of tumor resectability is difficult even wit help of CT. nonetheless CT would be very helfpul in management of patients having pancreatic cancer since CT would shorten the diagnostic procedures of pancreatic cancer.
