“…The Time-SLIP technique can be used to evaluate blood flow dynamics and pancreatic secretions. [2][3][4][5][6][7][8][9][10] Moreover, Time-SLIP has been used to evaluate CSF motion in the brain. 1,[11][12][13][14] Using Time-SLIP, we detected several CSF flow patterns that could not be resolved by traditional imaging.…”

“…Time‐SLIP is a technique based on arterial spin‐labeling methods; without the need for contrast material, it demonstrates the flow of blood, cerebrospinal fluid (CSF), pancreatic juice, and flow in the salivary gland duct . Although the Time‐SLIP technique can measure the travel distance of flow in 2D planes, we found no reports that quantified the volume flow rate (VFR, mm 3 /sec).…”

“…Some studies have evaluated the excretion flow dynamics of pancreatic juice and bile using cine‐dynamic magnetic resonance cholangiopancreatography (MRCP) with a spatially selective inversion recovery (IR) pulse 4,5 . These studies demonstrated that the secretion of bile and pancreatic juice was irregular and that reverse bile flow in the extrahepatic bile duct was a physiological phenomenon.…”

Background The physiological flow patterns and the reciprocal relationship between pancreatic juice and bile excretion dynamics have not been clearly elucidated by imaging. Purpose To assess the physiological flow patterns of bile and pancreatic juice simultaneously in order to clarify the pancreatobiliary flow dynamics using cine‐dynamic magnetic resonance cholangiopancreatography (MRCP) with a spatial selective inversion recovery (IR) pulse. Study Type Retrospective. Population A total of 85 patients with physiologically normal pancreatobiliary flow without ductal dilatation (normal group) and 19 patients with dilated pancreatic duct. Field Strength/Sequence A 3 T, fast spin echo sequence with IR pulse to nullify the signal of static pancreatic juice and bile. Assessment The frequency and secretion grade of the antegrade and reverse flow of the pancreatic juice and bile on cine‐dynamic MRCP were visually evaluated. Additionally, the reciprocal relationship between pancreatic juice and bile flow was evaluated based on its flow patterns. Statistical Tests Spearman's rank correlation coefficient analysis and the Kruskal–Wallis and Mann–Whitney U tests were used. P values of <0.05 were considered to indicate statistical significance. Results In the normal group, the antegrade pancreatic juice flow and no bile flow pattern was most frequently observed (29%), followed by the no pancreatic juice flow and no bile flow pattern (23%), the antegrade pancreatic juice flow and antegrade bile flow pattern (22%), and the no pancreatic juice flow and reverse bile flow pattern (9%). The flow of the pancreatic juice and bile were synchronized with each other in 47%, while they were not in 53%. In the dilated pancreatic duct group, the mean secretion grade of the antegrade bile and pancreatic juice flow was significantly lower than in the normal group. Data Conclusion Cine‐dynamic MRCP with a spatially selective IR pulse can visualize the variations of the physiological flow patterns of bile and pancreatic juice including 53% of unsynchronized patterns. Level of Evidence 4 Technical Efficacy Stage 5
