2、伴有門靜脈癌栓形成的DSA表現(xiàn),13例門靜脈癌栓腔內(nèi)缺損MRI表現(xiàn)為異常信號取代正常的門靜脈流空;4例門靜脈閉塞表現(xiàn)為門靜脈截斷;3例門靜脈彌漫性狹窄表現(xiàn)為門靜脈不規(guī)則狹窄。結(jié)論:MRI敏感性高,特征性強(qiáng),而且無創(chuàng)傷性。關(guān)鍵詞肝腫瘤門靜脈栓子MRI減影血管造影術(shù)中圖法分類號R735.7對手術(shù)評價、預(yù)后判斷和鑒別診斷有著重要意義。磁0引言共振成像(MRI)具有無創(chuàng)性、任意層面掃描及血管原發(fā)性肝癌常伴有門靜脈癌栓形成,癌腫直接成像等優(yōu)點。本研究比較20例原發(fā)性肝癌手術(shù)前門侵蝕靜脈壁進(jìn)而在靜脈腔內(nèi)生長形成癌栓,以阻塞靜脈癌栓的MRI和血管造影表現(xiàn),以
