Abstract

Magnetic resonance cholangiopancreatography (MRCP) is a method that can depict the main pancreatic duct non-invasively; however, its tendency to overestimate ductal stenosis is being noted. The authors used secretin to stimulate the output of pancreatic juice, which increased the signal of the main pancreatic duct and consequently minimized the occurrence of pseudostenosis artifacts in MRCP. MRCP images of 54 patients suspected of having pancreatic disease were visually evaluated by two observers before and after administration of secretin (1 clinical unit/kg). Improved delineation of the main pancreatic duct (68.5-59.3%, p < 0.05) and its side branches (40.7-29.6%, p < 0.05) was obtained with good interobserver agreement (kappa = 0.71-0.68).

摘要

磁共振胰胆管造影（MRCP）是一种能够无创显示主胰管的方法；然而，人们注意到它有高估导管狭窄的倾向。作者使用促胰液素刺激胰液分泌，这增加了主胰管的信号，从而减少了MRCP中假性狭窄伪影的出现。两名观察者在给予促胰液素（1临床单位/千克）前后，对54例疑似胰腺疾病患者的MRCP图像进行了视觉评估。主胰管（68.5 - 59.3%，p < 0.05）及其分支（40.7 - 29.6%，p < 0.05）的显示得到改善，观察者间一致性良好（kappa = 0.71 - 0.68）。
