鉴于目前的设备和检测手段，大部分原发性肝癌病例发现时已属晚期，手术切除率低，预后不良；而小肝癌（≤3cm）手术切除率高，术后五年生存率可达60％－70％。因此肝癌的早期发现和诊断具有重要的临床意义。一、小肝癌的CT检查和各种影像学方法比较从1989年－1992年，我们对20
In view of the current equipment and detection methods, most cases of primary liver cancer have been found late, with low surgical resection rate and poor prognosis; while small hepatocellular carcinoma (≤3cm) has a high surgical resection rate and the postoperative five-year survival rate can reach 60 %-70%. Therefore, early detection and diagnosis of liver cancer have important clinical significance. I. CT scans of small liver cancer and comparison of various imaging methods From 1989-1992, we compared 20
