【摘要】 目的 探讨采用磁共振胰胆管成像(MRCP)显示胆囊管的正常解剖及各种变异。方法在149例MRCP图像上,多角度、多方位观察并测量胆囊管长度及管径,观察并统计胆囊管走行、汇入位置、汇入方向及各种解剖变异。结果 MRCP上胆囊管显示清晰合计122例(82%),长度为(20.83±8.92)mm,直径为(2.82±1.04)mm。70%呈管状走行,30%呈扭曲状走行。66%胆囊管在肝外胆管全长中1/3汇入胆总管,上1/3占31%,下1/3占3%。右侧汇入占74%,左侧占3%,前和后占23%。73%斜角汇入,15%螺旋状,12%平行状。胆囊管变异占20%,其中54%平行走行,17%低位汇入,17%中间汇入,4%长胆囊管,4%胆囊管囊肿,4%变异右肝管。结论 MRCP可以较好地显示胆囊管解剖及各种变异,在临床上具有重要的应用价值。更多还原

【Abstract】 Objective To study the normal anatomy and variantions of the cystic duct demonstrated by MR cholangiopancreatography(MRCP).Methods On MRCP images in 149 cases,the length and diameter of the cystic duct were observed and measured.The courser,position and anatomic variantions of the cystic duct were also investigated.Results The cystic ducts were depicted well by MRCP in 122(82%).The average length and diameter of the cystic ducts were(20.83 ± 8.92) mm and(2.82± 1.04) mm,respectively,the course of cystic ducts was tubular in 70% and tortuous in 30%.The cystic duct inserted into the middle one-third of the extrahepatic bile duct in 66%,into the upper one-third in 31%,and into the distal one-third in 3%,entered from the right aspect in 74%,from the medial aspect in 3%,and from an anterior and posterior position in 23%.The cystic duct joined the common hepatic duct at an oblique angle in about 73%,spiral in 15% and parallel in 12%.Anatomic variant of the cystic ducts in 20%,runned parallel in 54%,jointed at low position in 17% and medial aspect in 17%,long cystic duct in 4%,cysts of cystic duct in 4%and anomalous right hepatic duct in 4%.Conclusion The anatomy and anatomic variantions of the cystic ducts can be depicted well by MRCP,which is of significant value clinically.更多还原
