Hepatic vessels injected with physiological saline via the portal vein are clearly shown as dark grey areas in the phase map. The phase map dynamically demonstrated the portal vein, capillary vessel area and hepatic vein sequentially. Frame 1: pre-injection; frames 2 to 4: portal phase; frame 5: capillary phase; frames 6 to 12: hepatic vein phase. Scale bar = 1 mm. |
