Figure 3 (A,B).
A 70-year-old man with distal common bile duct (CBD) cancer. MinIP (A) and inversion mode (B) images show that the intrahepatic ducts (IHD) and CBD are severely dilated due to a distal CBD lesion (arrow in B). The inversion mode tool transforms anechoic voxels into solid areas. MinIP : minimum intensity projection, RIHD = right intrahepatic duct, LIHD = left intrahepatic duct
