摘　　要：目的 探讨肝脏局灶性结节增生（FNH）的MSCT表现及诊断价值.方法 回顾性分析经病理证实的12例FNH的 CT平扫和多期增强扫描表现.结果 单发病灶12例.平扫：低密度9例,等密度2例,高密度1例.增强：动脉期所有病灶均快速显著增强,门静脉期所有病灶增强密度逐渐下降,延迟期10例病灶为等或稍低密度,2例为稍高密度轻度增强 4例病灶动脉期检出中央瘢痕,门静脉期及延迟期瘢痕密度逐渐增高而面积减少或消失 动脉期和门静脉期3例病灶周围可见增粗的供血动脉.结论 MSCT多期增强扫描对FNH具有特征性的诊断价值.Objective To investigate MSCT features and diagnostic value in hepatic focal nodular hyperplasia（ FNH） of the liver. Methods MSCT plain scans and dynamic scans in multiple phases in 12 cases with FNH proven pathologically were reviewed retrospectively. Results The lesions were all single in 12 patients. On plain scans, the lesions showed hypodensity in 9,isodensity in 2 and hyperdensity in one. After administration of contrast medium, all lesions were markedly and homogeneously enhanced in arterial phase and gradually decreased enhancement in portal phase,in delayed phase 10 cases displayed isodensity or slightly hypodensity, other 2 displayed slightly hyperdensity. There were 4 cases with central scars, which were found in arterial phase, the density of the scars gradually increased and the extents of the scars decreased or even disappeared in portal and delay period. Tough feeding arteriae were seen around the lesions in 3 cases in arterial and portal phase. Conclusion MSCT dynamic scan is of significant value in diagnosis of hepatic FNH.
