Objective To evaluate the curative effect of chemoembolization of liver tumors by using of diffusion-weighted imaging(DWI) magnetic resonance(MR).Method 6 clinic liver tumor patients and 2 rabbits with VX2 tumor in liver first underwent routine T_1-weighted and T_2-weighted imaging of the whole liver,and then underwent DWI by using of 2 different b factors under breath-hold or general anaesthesia.Results By using of different b factors,chemoembolization postoperative apparent diffusion coefficient(ADC)_{focus}/preoperative ADC_{focus}≥110%,the prognosis was better,while the value<110%,the prognosis was worse;postoperative ADC_{focus}ADC_{liver}/ preoperative ADC_{focus}ADC_{liver}≥110%,the prognosis was better,while the value<110%,the prognosis was worse.Conclusion It seems that DWI and ADC value can evaluate the curative effect after chemoembolization of liver tumors. |
