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。
In this paper, 8 cases of hepatic hydatid cysts confirmed by surgery and 5 cases of hepatic alveolar hydatid disease were analyzed by magnetic resonance imaging (MRI). Hydatid cysts showed a round, oval-shaped smooth edge of the image, T1 weighted image was low signal, T2 weighted image was high signal. Its characteristic manifestation is a smooth and even lesions with low signal intensity of the cystic wall and was multilocular ascus, an important basis for the MRI diagnosis of the disease. Bubble hydatid cysts were massive type, in the T1 and T2 weighted images were low signal, the state is not clear, the edge is not regular, the center of liquefaction and necrosis, was dissolved in lava, and occasionally granular calcification. Also explored the differential diagnosis of non-parasitic lesions and this disease.
