【Abstract】 Objective:Patterns of blood flow supply of 75 cases with hepatocellular carcinoma(105 lesions)and 54 cases with liver metastatic cancer(96 lesions)were analysed by color Doppler flow imaging to tender for diagnosis and differentiation diagnosis evidences.Methods:The hemodynamics parameter of the proper hepatic artery,the portal vein and the feeding vessels for tumor were presented by color Doppler spectrum.The measurement indexes are the maximum blood flow velocity(V max),the resistance index(RI),the pulsatility index(PI),the ratio of the maximum to minimum blood flow velocity(A/B)and the blood flow volume(FV).Results:The Vmax and FV of the proper hepatic artery and portal vein of the hepatocellular carcinoma(HCC) and liver metastatic cancer(LMC)group were higher than normal control group( P <0 001),however,the RI,PI and A/B ratio of the proper hepatic artery were lower than normal control.Pulsatory blood flow signals within the tumor were observed in HCC 82(91 1%)and “basket”pattern was found in 65(72 2%).The lesions of LMC showed mainly periphery flow pattern around tumor.Conclusion:Color Doppler flow imaging can improve accuracy of diagnosis and differentiation of HCC from LMC,but it is unreliable in deffrentiation of HCC from hypervascular LMC.更多还原
