Researchers have examined the possibility of studying pancreatic and biliary flow and using to aid the pathological evaluation of pancreaticobiliary diseases. Recently, a new method using MR imaging (MRI) has been developed for the direct visualization of pancreatic juice flow, based on a spin labeling technique. This technique enables direct visualization of pancreatic or bile duct juice flow and has various clinical applications relating to pancreaticobiliary disease. This review discusses the principle of pancreatic and biliary flow MRI with spin labeling and typical application examples such as the evaluation of the exocrine function of the pancreas in cases of chronic pancreatitis and the visualization of pancreatic juice reflux into the bile duct. Moreover other application is also discussed.
研究人员探讨了研究胰液和胆汁流动并用于辅助胰胆疾病病理评估的可能性。最近，基于自旋标记技术开发了一种利用磁共振成像（MRI）直接观察胰液流动的新方法。该技术能够直接观察胰管或胆管的液体流动，并在胰胆疾病方面有多种临床应用。本文综述了自旋标记胰胆流动MRI的原理以及典型应用实例，如慢性胰腺炎患者胰腺外分泌功能的评估和胰液反流至胆管的可视化。此外，还讨论了其他应用。
