K~(trans) of dynamic contrast enhanced MRI in evaluation of anti-angiogenic effects on nude mice with orthotopic transplantation tumor model of gastric cancer
Objective To assess the feasibility of Ktrans value of dynamic contrast enhanced MRI(DCE-MRI)in evaluation of anti-angiogenic effects on nude mice with orthotopic transplantation tumor model of gastric cancer.Methods Nude mice with orthotopic transplantation tumor model of gastric cancer were randomly assigned to two groups:Treatment group(n=15),mice were given apatinib intragastrically for 18days(100mg/kg),and control group(n=15),mice were given ddH2O2 in the same manner.After 18 days,DCE-MRI was performed...
