Background/aims: The aim of this study was to investigate whether exogenous dehydrocholic acid (DHCA) was useful to enhance the delineation of hepatolithiasis.
Methodology: 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 hepatolithiasis in 8 of 9 cases (88.9%).
Conclusions: It was suggested that administration of DHCA could enhance the delineation of the hepatolithiasis on MRCP images.
