Biliary - Normal Portal Triad without Doppler
Caption
The large, pulsatile inferior vena cava lies at the bottom of the screen. Anterior to it and from left to right we see the large portal vein and small, round hepatic artery. Just above the hepatic artery lies another tubular structure which presents hyperechoic walls and an anechoic lumen; this is the common bile duct. Dr. Felipe Urriola P.
