2、見(jiàn)中央瘢痕,動(dòng)脈期及門(mén)脈期瘢痕均未見(jiàn)強(qiáng)化,延遲期5個(gè)見(jiàn)中央瘢痕強(qiáng)化。增強(qiáng)掃描動(dòng)脈期除中央瘢痕外,8個(gè)FNH病灶明顯均勻強(qiáng)化,2個(gè)中等均勻強(qiáng)化;門(mén)脈期病灶密度下降,但均略高于或等于正常肝實(shí)質(zhì);延遲期病灶密度等于或略低于肝實(shí)質(zhì)。動(dòng)脈期4個(gè)病灶中心或周邊見(jiàn)增粗的供血?jiǎng)用},其中1個(gè)為肝動(dòng)脈分支直接進(jìn)入病灶中心,1個(gè)的供血?jiǎng)用}自病灶中心沿纖維間隔向周邊呈放射狀分布,另2個(gè)周邊見(jiàn)供血?jiǎng)用}。結(jié)論:MSCF多期掃描可反映病灶的血供特點(diǎn)和病理學(xué)特征,對(duì)FNH具有重要的診斷及鑒別診斷價(jià)值。[關(guān)鍵詞]局灶性結(jié)節(jié)狀增生;肝;體層攝影術(shù),x線計(jì)算機(jī)MSC
