Assessment of Hemodynamics in a Rat Model of Liver Cirrhosis with Precancerous Lesions Using Multislice Spiral CT Perfusion Imaging
Figure 1
The TDCs obtained during perfusion imaging. (a) The TDC of the abdominal aorta showed a rapid increase and the time to peak was s. (b) The TDC of the portal vein showed a slow increase and the time to peak was s. (c) The TDC of the liver parenchyma showed a slow increase and the time to peak was s. (d) The hepatic arterial phase. The abdominal aorta showed obvious enhancement, while the portal vein was not clearly displayed. (e) The hepatic portal venous phase. The trunk of the portal vein and the left branch showed obvious enhancement. (f) The delayed phase. The liver parenchyma showed obvious homogeneous enhancement, while enhancement of the abdominal aorta and portal vein decreased.
