Accuracy of magnetic resonance cholangiography compared to operative endoscopy in detecting biliary stones, a single center experience and review of literature

Figure 1 Little stones in left branch of biliary tree (arrow).

Figure 2 Pre-papillary micro stones (arrow) fake stone in right branch of biliary tree (curved arrow).

Figure 3 (Same patient of Figure 2) next image shows the fake stone as biliary branches crossing (curved arrow).

Figure 4 Stricture or stones (arrow) at origin of common bile duct (A) and stricture (arrow) confirmed at endoscopic retrograde cholangiopancreatography but the balloon-catheter pulled out micro stones and no stricture was confirmed at control (B).

Figure 5 Pre-papillary stricture (arrow) microstones in right and left branch (curved arrows, confirmed at endoscopic retrograde cholangiopancreatography).

Figure 6 Micro stones in gallbladder (curved arrow), pre-papillary stenosis (arrow) (A) and endoscopic retrograde cholangiopancreatography shows pre-papillary stone (arrow), not the micro stones that were pulled out by balloon-catheter (B).
