| ［摘要］ 目的 探讨超声造影和增强CT对微小肝癌的诊断价值。方法 对影像学检查疑为恶性的112例143个≤2.0 cm的肝脏病灶分别行超声造影和增强CT检查，结果与病理对照，比较两种检查技术对微小肝癌的鉴别诊断效能。结果 112例143个病灶中，超声造影和增强CT诊断恶性、良性病变分别为103个、40个和100个、43个。病理诊断恶性病变111个，其中原发性肝细胞肝癌（HCC）79个（高、中、低分化癌分别为19、38、22），肝内胆管细胞癌（ICC）8个（高、中、低分化癌分别为4、3、1），转移性肝癌（MC）24个；良性病变32个。与病理对照，超声造影和增强CT诊断的敏感性、特异性、准确性分别为88.3%、84.4%、87.3%和86.5%、87.5%、86.7%，两者比较差异无统计学意义（P>0.05）。结论 超声造影和增强CT诊断微小(≤2.0 cm)肝癌具有相似的效能，超声造影更简便，具有重要的临床应用价值。 |

| Abstract: |
| ［Abstract］ Objective To investigate the value of contrast-enhanced ultrasound(CEUS) and contrast-enhanced CT(CECT) in the diagnosis of small liver cancer.Methods One hundred and tweleve patients with 143 small solid liver lesions (≤2.0 cm) were examined with contrast-enhanced ultrasound and contrast-enhanced CT, and the diagnoses were confirmed by pathological examination. CEUS and CECT findings of 143 small solid liver lesions in the patients were retrospectively analyzed.Results 111 malignant lesions including 79 primary liver carcinoma, 8 intrahepatic cholangiocarcinoma and 24 metastatic liver carcinoma and 32 benign lesions were found in 112 patients with 143 lesions. Compared with the results of pathological diagnosis, the sensitivity, specificity and accuracy of CEUS and CECT were 88.3%, 84.4%, 87.3% and 86.5%, 87.5%, 86.7%, respectively, without significant differences between CEUS and CECT in the diagnosis （P>0.05）.Conclusion CEUS and CECT have similar effects in the diagnosis of small liver carcinoma(≤2.0 cm). CEUS is simpler than CECT in the diagnosis of small liver carcinoma. |
