摘要:
目的探讨利用磁共振DWI 序列及表观扩散系数(ADC)值动态评估原发性肝癌介入治疗疗效的价值。方法对介入治疗前、后的患者进行常规MRI 、动态增强及DWI 序列(弥散梯度因子b=0、200、500、800s /mm 2 )扫描,测量0~500的ADC值,并与血管造影、血清生化对比。结果介入治疗后肿瘤的ADC值较术前增高,疗效好的ADC值>疗效中等的ADC值,与术前比较均有统计学意义,疗效差的ADC值与术前差异无统计学意义;随访显示ADC值无明显降低的为疗效好的病例,疗效中等和差的ADC值出现降低,增强MRI 、DWI 序列、血管造影可显示癌细胞存活、复发。结论DWI 序列和ADC值可以动态观察原发性肝癌介入治疗后癌细胞是否坏死、存活和复发,可及时有效的评估介入治疗疗效。
