Abstract: Objective To explore the value of high-field-strength MRCP in diagnosing of intraductal papillary mucinous neoplasms (IPMNs)of pancreas.Methods Fifteen cases with IPMNs confirmed surgically and pathologically were recruited.The magnetic res-onance imaging (MRI)and MRCP findings were retrospectively analyzed.Results All cases were benign,including main pancreatic duct type (MPD)in 1,branch pancreatic duct type(BPD)in 8,and the combined type in 6.The MPD type showed diffuse dilation of main pancreatic duct which is about 14.5 mm with no enhancement.The BPD type displayed unilocular or multilocular cystic le-sions which showed communication with main pancreatic duct .The combined type demonstrated dilation of main pancreatic duct and branch pancreatic duct.The septa and mural nodule in the BPD type and the combined type were moderately enhanced.Conclusion MRCP is superior with regard to the diagnosis and classification of IPMN type and is helpful to differentiate malignant tumors from benign ones combined with routine contrast-enhanced.
