Figure 5
The time density curve of hepatic blood flow. The transit of physiological saline is clearly shown from the portal vein to the hepatic vein. The peak times of the portal vein, capillary area and hepatic vein were about 4.8 s, 19.2 s and 28.8 s, respectively. The overlapped image of the portal phase and venous phase helps to demonstrate the anatomical position of the portal vein and hepatic vein exactly. PI value means the difference in refractive index between vessel and surrounding liver + refractive index of physiological saline normalized as 1.00 in the background.
