目的探讨三维超声胆管造影技术显示肝内胆管的可行性.方法对5个离体猪肝不同肝叶的胆管分别进行插管,经插管注入1:20稀释的SonoVue超声造影剂后进行三维超声造影检查,分别评价可分辨最高胆管分支级别和图像质量,并与X线胆道造影作比较,评价其胆管树形态拟合度.结果在5个离体猪肝中成功插管14个分叶,最高可显示至第3级分支,最高显示级别为第3、2、1级分支的比例依次为42.9%(6/14)、42.9%(6/14)、14.2%(2/14);图像质量优、中、差的比例依次为21.4%(3/14)、57.2%(8/14)、21.4%(3/14);与X线胆道造影比较,图像拟合度优、中、差的比例依次为42.9%(6/14)、42.9%(6/14)、14.2%(2/14).结论三维超声胆管造影技术可能是一种显示胆管树解剖结构的全新影像学方法.

Objective To investigate the feasibility of three-dimensional contrast-enhanced ultrasonic cholangiography(3D-CEUSC) in isolated porcine liver specimens.Methods The lobes of 5 isolated porcine livers were taken as scanning units and the lobular bile branches were cannulated.3D-CEUSC was performed after the administration of diluted ultrasonic contrast agents(SonoVue) through the cannula.The images were assessed in term of maximum visualization of branching orders and image quality.The coincidence of morphous was compared between 3D-CEUSC and cholangiagraphy using fluoroscopy.Results Fourteen lobular biliary branches were cannulated successfully in 5 isolated porcine livers.The maximum visualization of branching orders from the third- to first-order branches were 42.9% (6/14) ,42.9% (6/14), 14.2% (2/14) in sequence.The image quality was 21.4% (3/14) graded as well, 57.2% (8/14) as moderate, and 21.4% (3/14) as poor.Compare with cholangiagraphy using fluoroscopy, the coincidence of morphous was 42.9%(6/14) for well,42.9% (6/14) for moderate,and 14.2% (2/14) for poor.Conclusions 3D-CEUSC could be a new imaging method to evaluate the biliary anatomy.
