Multiplanar reformations and minimum intensity projections using multi-detector row CT for assessing anomalies and disorders of the pancreaticobiliary tree

Figure 3 A small stone in the common bile duct of a 34-year-old woman with epigastric pain. A: MinIP (coronal oblique 6.2 mm thickness slab) image shows mild dilatation of the extrahepatic bile duct without delineation of the stone; B: MinIP (coronal oblique 3.8 mm thickness slab) image with a slab thickness that is thinner than the size of the stone shows the stone (black arrow) in the distal common bile duct; C: MRCP demonstrates the low signal intensity of the stone (white arrow) in the distal common bile duct.
