Experimental study of three-dimensional contrast-enhanced ultrasonic cholangiography in isolated porcine liver specimens / 中华超声影像学杂志

ABSTRACT

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.
