| 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 anastomotic site. METHODOLOGY: DHCA is a cholagogue which produces an immediate effect by acting directly on liver cells. Its choleretic effect is strong, appearing 1 to 3 minutes after intravenous injection, reaching the maximum level in 20 to 30 minutes. Our study population comprised 9 patients. Magnetic resonance cholangiopancreatography (MRCP) 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. RESULTS: DHCA provided a better visualization of the anastomotic site in 7 patients (77.8%). The two patients without improvement in visualization of anastomotic site included 1 patient with liver cirrhosis secondary to portoenterostomy for ongenital biliary dilatation and 1 patient, who was not eligible for the evaluation because of motion artifact caused by the difficulty of breath holding motion artifact. CONCLUSIONS: It was suggested that administration of DHCA could enhance the delineation of the anastomotic site on MRCP images. |
