Figure 1 The measurement method.
A: Measurement of the common bile duct (CBD) diameter by placing an electronic caliper at the widest visible portion of the CBD on magnetic resonance cholangiopancreatography (MRCP); B: Measurement of the length of the extrahepatic bile duct on MRCP. It is the sum of the length from the hepatic hilum to the tortuous portion and from the tortuous portion to the ampulla; C: Measurement of the length of the CBD on MRCP. It is the sum of the length from the cystic duct insertion to the tortuous portion and from the tortuous portion to the ampulla; D: Measurement of the portal vein anteroposterior diameters by placing the electronic caliper at the splenic veins into the portal vein on T2-weighted images.
