肝癌(原发和转移癌),肝海绵状血管瘤是肝内常见的占位性病变,正确诊断对选择治疗方案十分重要。大多数肝癌具有突出的MR征象:T_1-WI病灶信号较低,均匀或不均匀,边界清楚,形态多为不规则形或分叶状,肝内血管变形、受压、移位。T_2-WI病变多呈高、中、低混杂信号,有假包膜及占位效应,出血时信号则异常增高,一般与肝海绵状血管瘤鉴别不难。但少数病例,特别是一些单个结节型肝癌往往不具上述征象,而类似于肝海绵状血管瘤的表现:呈结
Liver cancer (primary and metastatic cancer), hepatic cavernous hemangioma is a common occupying lesion in the liver, the correct diagnosis of the choice of treatment is very important. Most of the liver cancer has prominent MR signs: T_1-WI lesion signal is low, uniform or non-uniform, the border is clear, the shape of mostly irregular or lobulated, intrahepatic vascular deformation, compression, displacement. T_2-WI lesions were mostly high, medium and low mixed signal, a pseudocapsule and space-occupying effect, the signal was abnormally increased bleeding, the general identification with the cavernous hemangiomas is not difficult. However, a small number of cases, especially some single nodular liver cancer often do not have the above signs, and similar to the performance of hepatic cavernous hemangiomas:
