摘要 目的分析肝脏局灶性结节增生的超声、CT及MRI表现及它们在临床诊疗中的价值,提高对本病的认识。方法10例确诊的FNH均行超声、螺旋CT检查,6例行MRI检查。结果10例FNH超声检查呈低回声者4例,等回声者3例,混杂回声者3例。术前诊断为FNH3例。CT平扫呈低密度者4例,等密度者6例,4例肿块周围可见粗大、扭曲血管影,4例显示中心瘢痕。术前诊断7例。MRI检查T1WI、T2WI呈等、高信号5例,呈低信号1例;3例见"星状瘢痕征";2例增强均呈多血供特征。术前诊断5例。结论CT、MRI检查,特别是动态增强及图像后处理技术是诊断FNH最有效的影像学方法,对指导外科治疗具有一定的价值;而超声检查对无症状者病灶的检出及筛查非常重要;综合分析临床及影像学表现,可提高诊断准确率。
