【摘要】目的 提高对肝脏局灶结节性增生CT表现的认识，探讨多层螺旋CT的诊断价值。 材料和方法 对8例经多层螺旋CT多期增强扫描并已病理证实FNH的病例,进行影像学分析。结果 7例为单发病灶，1例为2个病灶。CT平扫7个病灶呈低密度,2个为等密度； CT强化特点：病灶动脉期快速显著增强而门静脉期及延迟扫描为等密度，7个病灶检出瘢痕；结论 多层螺旋CT多期增强扫描能够显示FNH的增强特征性改变。

【Abstract】Objective To investigate MSCT findings of hepatic focal nodular hyperplasia（FNH），so as to improve its diagnostic value. Methods Three-phasic MSCT scans in 8 cases with 9 FNH were reviewed retrospectively,all of lesi as are proven pathologically. Results The lesions were single in 7 cases , double in 1 cases. 7 lesions is hypodensity and 2 lesions is isodensity on plain MSCT. During MSCT enhancement all lesions were markedly and homogeneously enhanced in arterial phase, isodensity in portal and delay plase, 7 lesions finded scar . Conclusion Dynamic contract-emhanced MSCT can show emhanced charcteristic of FNH.
