Preliminary study of hepatic perfusion imaging in canine with 64-slice spiral CT

【Objective】The purpose of the study was to explore the feasibility and accuracy of quantify- ing the blood flow volume of liver in healthy canine.【Methods】Philips 64-slice spiral CT perfusion scans of liver were performed in 12 healthy dogs.The time-density curve was drawn and liver perfusion parameters were counted using specialized liver perfusion analysis software.【Results】Regularity was revealed in the curves of corresponding organs.The hepatic artery perfusion,portal vein perfusion,total hepatic blood flow,artery perfusion index were(28.25±2.19)mL/(min·100 g),(53.53±10.71)mL/(min·100 g),(81.78±18.56)mL/(min·100 g)and(0.30±0.16)%,respectively.【Conclusion】It’s feasible to quantitatively evaluate the hemodynamics of liver in healthy dogs at a 64-slice spiral CT,and the 64-slice spiral CT scans can overcome the deficiency of the past.
