摘要 [目的]评价肝细胞癌磁共振扩散加权成像(DWI)及表观扩散系数(ADC)值与肿瘤细胞密度、微血管密度的相关性。[方法]60例肝细胞癌患者行DWI扫描,测量并计算病灶的ADC值,其中12例外科手术切除病灶行肿瘤细胞密度及微血管密度检测,并进行统计学相关性分析。[结果]肝细胞癌病灶平均ADC值为(1.15±0.23)×10-3mm2/s,正常肝组织平均ADC值为(1.71±0.30)×10-3mm2/s,两者差异有统计学意义(P<0.001)。平均肿瘤细胞密度为0.80±0.14,微血管密度为78.67±32.17,肝细胞癌ADC与肿瘤细胞密度呈负相关(r=-0.873,P<0.001),与微血管密度呈正相关(r=0.731,P<0.05)。[结论]磁共振DWI及ADC值能够反映肿瘤组织微观结构状态,对评价肿瘤的治疗及预后具有较高临床实用价值。
