| 内容記述 | Background/Aims: The aim of this study was to investigate whether exogenous dehydrocholic acid (DHCA) was useful to enhance the delineation of the biliary tree. Methodology: Our study population comprised 14 patients. Magnetic resonance cholangiopancreatography was acquired before and after the administration of DHCA. Two different MRCP snap shot techniques were applied: thick-slab two-dimensional (2D) (coronal) single shot turbo spin echo T2-weighted sequences and multisection thin-slab, 2D (coronal) single shot turbo spin echo T2-weighted sequences with three-dimensional (3D) maximum intensity projection (MIP) post processing. Volume rendering was prepared based on the source images, and the pixel size was visually adjusted to the biliary area of MRCP to measure the biliary tree volume. Results: DHCA increased the bile duct volume in 13 of the 14 patients. It provided a better visualization of the biliary tree in 11 patients. The three patients without improvement in visualization included 1 patient with liver cirrhosis secondary to portoenterostomy for congenital biliary dilatation and 2 patients with cholecystectomy who had the bile ducts filled with bile by the time of the ministration. Conclusions: It was suggested that administration of DHCA could enhance the delineation of the biliary tree on MRCP images. |
