Outline of Final Research Achievements

Visualization of the secretory flow of the bile and pancreatic juice will be important to assess the pathophysiology of the pancreatobiliary system, especially pancreatic exocrine functions as well as the function of Oddi sphincter. Secretin-stimulated MRCP may help assess the pancreatic juice flow by the caliber change of main pancreatic duct before and after secretin administration. However, this method is invasive, and observes non-physiologic information. Additionally, this method can not visualize the pancreatic juice flow directly. This study enabled us to visualize the physiological flow of the bile and pancreatic juice non-invasively by means of non-pharmacological MRCP with spatially selective inversion recovery pulse, and showed the feasibility of this technique for the assessment of pancreatic exocrine functions as well as the function of Oddi sphincter.
