摘要: PURPOSE: To evaluate the frequency of artifact from arterial pulsatile compression as cause pseudo-obstruction extrahepatic bile duct at magnetic resonance (MR) cholangiopancreatography (MRCP) and specify causative vessels. MATERIALS AND METHODS: In 234 patients (102 men, 132 women; age range, 25–80 years), MRCP images obtained by using a single-shot turbo spin-echo sequence were reviewed to assess caused vascular compression. Dual-phase spiral computed tomography, contrast material–enhanced three-dimensional MR angiography, and/or digital subtraction angiography also performed determine vessel that pseudo-obstruction. RESULTS: Thirty-six pseudo-obstructions due found in 33 (14%) patients. The common hepatic (27 [75%] sites) was most site, followed left (four [11%] sites), proximal (three [8%] right hep...
