摘　　要：目的:通过分析肝局灶性结节样增生的CT征象,提高对本病的诊断准确率。方法:对10例经病理证实的肝局灶性结节样增生的CT征象进行回顾性分析。结果:10例均为单发病灶,结节状或分叶状肿块,直径平均约为4.3cm。平扫为稍低或等密度;动脉期除中央瘢痕外均明显强化,接近于同层腹主动脉密度,病灶内可见增粗的供血动脉;门脉期呈稍高密度7例,等密度3例;平衡期及延迟期呈稍高密度3例,等密度7例;4例病灶的中央瘢痕3例出现延迟强化,1例未见明显强化。结论:肝局灶性结节样增生在螺旋CT三期增强扫描中有特征性表现。Objective：To evaluate the CT findings of focal nodular hyperplasia（FNH） of the liver,and to raise the diagnostic accuracy of the disease.Methods：CT manifestations of the 10 patients with FNH proved pathologically were analyzed retrospectively.Results：10 cases were single lesion,and showed nodular or lobulated mass.The average diameter was 4.3 cm.On plain CT,the lesions were demonstrated iso-density or slightly hypo-density.On images of arterial phase,all the lesions were enhanced obviously,the density was close to abdominal aorta,except for the central scar.The thickening feeding artery was seen in the lesions.7 cases showed moderate hyperdensity and 3 cases showed isodensity during the portal vein phase.3 cases showed mild hyperdensity and 7 cases showed isodensity during the equilibrium and delay phase.3 of 4 cases of the central scars showed delayed enhancement.Conclusion：FNH has the characteristic performance in tri-phase enhancement spiral CT scanning.
