原发性肝癌是我国常见的恶性肿瘤,临床上发现的早期小肝癌(SHCC)均能明显提高5年生存率,降低复发率[1]。SHCC的早发现成为临床治疗肝癌的关键,因此,影像学在早期诊断小肝癌的应用中意义重大。1SHCC诊断标准我国一般采用中国肝癌病理协作组织的标准,以直径≤3cm(单个肿瘤结节直径≤3cm或癌结节数量不超过2个,其直径的总和≤3cm的肝癌)为标准。临床上仍以经皮肝穿刺病理组织学检查作为诊断SHCC的标准,但由于经皮肝穿刺活检操作复杂,有风险并可导致癌细胞转移,且不宜反复操作;而血清甲胎蛋白(AFP)又有一定比例的假阴
Primary liver cancer is a common malignant tumor in our country. Clinically found early small hepatocellular carcinoma (SHCC) can significantly improve the 5-year survival rate and reduce the recurrence rate [1]. The early detection of SHCC has become the key to the clinical treatment of liver cancer, therefore, imaging in the early diagnosis of small liver cancer is of great significance. 1SHCC diagnostic criteria China’s standardization of China’s liver cancer pathology organization to standard diameter ≤ 3cm (single tumor nodules ≤ 3cm or no more than two cancer nodules, the total diameter of ≤ 3cm of liver cancer) as the standard. Percutaneous liver biopsy is still used clinically as a standard for the diagnosis of SHCC. However, due to the complexity of percutaneous transhepatic biopsy, it is risky and may lead to cancer metastasis, and should not be repeated. Serum alpha-fetoprotein (AFP) There is a certain percentage of false negatives
