【摘要】目的探討磁共振胰膽管成像（magnetic resonance cholangiopancreatography, MRCP）技術(shù)在肝外膽管梗阻中的診斷價值。
方法收集我院2004年收治的42例膽管梗阻患者的MRCP檢查臨床資料，分析良、惡性肝外膽管梗阻在MRCP上的不同表現(xiàn)。
結(jié)果MRCP檢查在30例良性梗阻患者主要表現(xiàn)為膽管均勻擴張及逐漸狹窄，管壁均勻增厚，斷端可呈“鳥嘴樣”，其在良性梗阻中的定位及定性準確率分別為100%（30/30）和97%（29/30）； 12例惡性梗阻患者中主要表現(xiàn)為膽管不均勻?qū)ΨQ擴張及突然狹窄或截斷，管壁不均勻增厚，可出現(xiàn)“雙管截斷征”，其在惡性梗阻中的定位及定性準確率分別為100%（12/12）和92%（11/12）。
結(jié)論MRCP是一種無創(chuàng)性顯示胰膽管管腔形態(tài)學改變的影像學方法，在評價肝外膽管梗阻中具有較好的定位及定性準確率。
