Research of Perfusion Weighted Imaging of Different Liver Lobe

Objective:To research the perfusion weighted-imaging value of different liver lobe.Methods:14 cases of healthy adults were scanned by MRI.The side slices of liver that contained left medial lobe,left lateral lobe,right anterior lobe,right posterior lobe simultaneously was scanned with PWI.The hepatic perfusion parameters including arterial phase and portal vein phase,the most slopes around the peak value of spleen perfusion,calculated on the basis of time-signal curve.The results were classified according to the different liver lobe.The analysis of variance was applied with SPSS for Windows 12.0 (size of test α=0.05).Results:The blood volume perfusion exists significant difference between left liver lobe and right liver lobe .Conclusion:The proportion of arterial blood in left lobe is bigger than right lobe,the proportion of portal vein blood in right lobe is bigger than left lobe.
