Abstract：Objective To investigate the value of CT perfusion technique in evaluating hemodynamics changes of portal vein pressure of gastrointestinal diseases (PHGE) .Methods Twenty healthy volunteers (control group) and twenty-six patients with PHGE were examined using CT perfusion .The blood flow (BF) ,mean transit time (MTT) ,permeability (PMB) ,time to peak (TTP) and blood volume (BV) of descending duodenum were recorded .These parameters of perfu-sion of two groups were analyzed using SPSS 13 .0.Results BF value of control group and PHGE were (173 .02 ± 85 .14) ml/100g tissue /min and (82 .52 ± 52 .37) ml/100g tissue/min ( P=0.003) .MTT of control group and PHGE group were(10.78±2 .65)s and (16.32 ± 3.74) s .( P=0.003);PMB were (36.79±22.14) ml/100g tissue/min and (22.36±11.02) ml/100g tissue/min .( P=0.005) .No differences between control group and PHGE were found in TTP (P=0.485) and BV (P=0.327) .Conclusion Deceased BF ,PMB and prolonged MTT of gastrointestinal tract of PHGE suggested that CT perfusion can evaluate the hemodynamics quantitatively in PHGE .
