摘要 目的分析肝脏局灶性结节增生(FNH)平扫和动态增强的螺旋CT、MRI表现,提高FNH诊断符合率。方法对15例经手术病理证实的FNH影像学表现进行回顾分析。结果8例CT平扫病灶呈低密度或等密度。增强动脉期扫描除中心瘢痕外,所有病灶均有明显均匀强化,其中3例还可见到病灶中心或周边增粗、扭曲的动脉。门脉期和延迟期扫描4例呈略高密度、2例病灶呈等密度或略低密度,2例伴有中心瘢痕者均有延迟强化。MRI检查9例,病灶均呈不均匀略长或等T1及T2信号,增强动脉呈明显强化,门脉期及延迟期呈等或略高强化。结论平扫和动态增强螺旋CT、MRI能较全面显示FNH的病理特征和血供特点,明显地提高与其他富血管恶性肿瘤的鉴别诊断能力。
