Ct Perfusion Imaging In The Diagnosis And Differential Diagnosis Of Renal Cell Carcinoma Application Value

Objective To discuss the value of CT perfusion imaging in diagnosis of renal cell carcinoma.Methods Perfusion was performed in 30 cases of normal renal cortex and 30 cases of affection in renal parenchyma with pathologically proved clear,including 15 cases of renal carcinoma(RCC), 8 cases of renal agiomyolipoma(RAML), 4 cases of renal cyst(RC), 3 cases of renal abscess(RA).Before surgery,a single level through the renal hili or affection in renal parenchyma was scanned after the intravenous injection of 40 ml of contrast given at 5 ml/s,and then the parameters including blood flow(BF),blood volume(BV),mean transit time(MTT),permeability surface(PS) and time-density curve(TDC) were analyzed using GE perfusion software.Results The parameters of RCC including BF,BV,MTT,PS were significantly different from the parameters of normal renal cortex and other affection in renal parenchyma,P<0.05.Conclunsions There is some value of CT perfusion imaging in diagnosis of renal cell carcinoma.
