【摘要】目的探討磁共振胰膽管成像（magnetic resonance cholangiopancreatography, MRCP）技術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。
結果MRCP檢查在30例良性梗阻患者主要表現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為膽管不均勻對稱擴張及突然狹窄或截斷，管壁不均勻增厚，可出現“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）。
結論MRCP是一種無創性顯示胰膽管管腔形態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。
