摘　　要：本文对手术证实的８例肝包虫囊肿及５例肝泡状棘球蚴病的磁共振成像（ＭＲＩ）进行分析。包虫囊肿表现为圆形、卵圆形边缘光滑的影像，Ｔ１加权像呈低信号，Ｔ２加权像呈高信号。其特征性表现为病变有光滑均匀的低信号强度的囊壁及呈多房性的子囊，为ＭＲＩ诊断本病的重要依据。泡状棘球蚴呈巨块型，在Ｔ１和Ｔ２加权像上均呈低信号，境界不清，边缘不规整，中心液化坏死，呈溶岩状，偶见颗粒状钙化。还探讨了本病与非寄生虫性占位病变的鉴别诊断。The MRI findings of 8 patients with cystic hydatid and 5 patients with alveolar hydatid were reported.The main MRI features of the cystic hydatid revealed as a round or oval shape with smooth margin and low signal intensity on T1 weighted sequence,and high signal intensity on T2 weight sequence. The predominant sign were a smooth intensity cystic wall and multicystic when daughter cysts are existed. The MRI findings of alveolar hydatid were a large mass with low signal intensity both on T1 and T2 weight sequence.
