诊断肝占位病变和随访其发展过程的现有两种检查方法是扫描和选择性肝动脉造影。用同位素金(~(198)Au),碘(~(131)I)或锝(~(99)Te)在扫描肝实质占位病变时,图象不能说明病变的性质,解释有时很困难;又如当病变直径较小,位于边缘或肝左叶以及肝硬变时,假阴性的出现率亦随之而增加。本文报道 The two existing methods of diagnosis of liver space-occupying lesions and their follow-up are scanning and selective hepatic arteriography. Interpretation can sometimes be difficult when using isotope gold (~ (198) Au), iodine (~ (131) I) or technetium (~ (99) Te) Another example is when the lesion diameter is smaller, located in the edge or left lobe and liver cirrhosis, the incidence of false negatives also will increase.
