MRI/MRCP abdomen with and without contrast is a reasonable test to further characterize pancreatic cysts/cystic lesions.
Pancreatic cystic lesions can represent pseudocysts (if history of
pancreatitis or trauma), sidebranch IPMN (benign), serous cystic neoplasm (benign), or mucinous cystic neoplasms (not benign). It is helpful to include MRCP sequences for better evaluation of biliary and pancreatic ducts.
