Abstract:
Objective To study 64-slice CT perfusion features of metastatic tumors of liver and its clinical value.Methods 23 cases (40 lesions) with liver metastases underwent CT perfusion scanning.Hepatic arterial perfusion index(HPI) parameters including blood flow perfusion(BF),patlak blood capacity (pBV),vascular permeability (P,permeability),arterial liver perfusion(ALP),portal venous perfusion( PVP ) were analyzed in comparison with that of normal liver .Results (1)BF, pBV , P , ALP , PVP and HPI in normal liver tissue were (47.85?8.11) ml?100ml-1?min-1,41.25?6.32 (1000:1), 64.25?11.10 (0.5 ml?100ml-1?min-1),(24.55?2.96) ml?100ml-1?min-1, (105.24?16.42) ml?100ml-1?min-1,(20.18?3.81),respectively.(2)BF,pBV,P,ALP and PVP between the normal hepatic tissue and the centre of lesions were of statistically significance (P
