Diagnostic Value of Dynamic Contrast-Enhanced Magnetic Resonance
Imaging in the Evaluation of the Biliary Obstruction
Figure 2
MRCP image demonstrates (a) a calculus (white arrow) located in the distal common bile that does not cause bile duct dilatation. This calculus was not detected during the MRI examination and received a false negative diagnosis. (b) ERCP image demonstrates the calculus (black arrow). This calculus was extracted during the procedure.
