Abstract:
Objective To study the applied value of MR DWI and ADC value of in the hepatic lesions.Methods 36 cases ofhepatocellular carcinoma,15 cases of metastases,33 cases of hepatic cavemous hemangioma and 12 cases of cyst were examined by DWI andconventional MRI,then the ADC values were measured.Results The average ADC values of hepatic lesions were as follows:cyst was(2.90?0.68)?10~(-3)mm~2/s,hemangioma was(2.01?0.53)?10~(-3)mm~2/s,metastases was(1.57?0.42)?10~(-3)mm~2/s,hepatocellular carcinoma was(1.20?0.32)?10~(-3)mm~2/s.The ADC values of benign lesions were higher than those of malignant(P
