摘要
笔者分析了经病理组织学证实的１８例小肝癌与７例非囊肿，非血管瘤良性病变（≤３．０ｃｍ）的ＭＲＩ（１．０Ｔ）表现。结果表明：Ｔ_１ＷＩ上稍低信号，等或稍高质子密度，Ｔ_２ＷＩ上稍高信号，内部信号不均匀，Ｔ_２值＜９０ｍｓ是小肝癌典型的ＭＲＩ表现。Ｔ_１ＷＩ稍低信号，等或稍低质子密度，Ｔ_２ＷＩ等或稍低信号是本组良性病变的ＭＲＩ征象。ＭＲＩ对本组病例的定性准确率约９２％。ＭＲＩ对小肝癌的诊断和鉴别诊断具有重要价值。
primary small hepatic carcinomas(PSHC)and 7 noncystic, nonhemangioma benign lesions(≤ 3.0cm)proved pathologically were studied by M R imaging at 1.0T. Slight hypointensity on T_1WI, slight hyperintensity on T_2WI with heterogeneous pattern and T_2 value<90 ms were the characteristic signs of PSHC. Slight hypointensity on T_1WI and T_2WI, or isointensity on T_2WI were the appearance of the benign lesions, The accuracy of MRI for our group was about 92%. M RI played an important role in differential diagnosis of PSHC
