Abstract:Objective To analyze the value of multi-slice spiral computed tomography (MSCT) and magnetic resonance image (MRI) for the diagnosis of pancreatic intraductal papillary mucinous tumor. Methods Twenty-six patients with pancreaticintraductal papillary mucinous tumor collected from February 2015 to February 2018 were randomly selected in whom MSCT plain scan and enhanced scan were performed in 20 cases, while MRI plain scan and enhanced scan and magnetic resonance cholangiopancreatography (MRCP) were performed in 6 cases. MSCT and MRI image data were analyzed. Results Out of 26 cases, 20 were diagnosed by MSCT. MSCT plain scan and enhanced scan showed:Main pancreatic duct type was seen in 3 cases, and branch pancreatic duct type was seen in 16 cases，10 cases were located in head of the pancreas (5 cases of borderline tumor, 5 cases of adenoma); 6 caseslocated in body of the pancreas (5 cases of adenoma, 1 case of adenocarcinoma). Onset site of 1 case of mixed type was seated in head of the pancreas. Out of 6 cases diagnosed by MRI, the onset site of 3 cases was located in head of the pancreas, and 3 cases was located in pancreatic tail. Out of 26 cases diagnosed by pathology, borderline tumor, adenocarcinoma and adenoma were 6 cases (23.1%), 4 cases (15.4%) and 16 cases (61.5%), respectively. Conclusion Both MSCT and MRI have higher clinical value for the diagnosis of pancreatic intraductal papillary mucinous tumor.
