目的 比较超声造影及CT增强扫 描在肝细胞癌诊断中的临床价值。方法 选择医院2016年4月-2018年4月收治的肝 细胞癌患者80例，所有患者均接受超声造 影和CT增强扫描检查。比较超声造影和CT 增强扫描的增强特点、表现特点、增强百 分率及准确性，并记录肿瘤内血管形态及 坏死区显像形态。结果 超声造影和CT增 强扫描检查的增强特点、表现特点、增强 百分率结果相差甚微，差异无统计学意义 (P＞0.05)。超声造影的准确度高于CT增 强扫描，差异有统计学意义(P＜0.05)。 结论 超声造影与CT增强扫描检查相比， 增强模式及增强百分率相一致，但其准确 性更高。

Objective To compare the clinical value of contrast-enhanced ultrasound and CTenhanced scan in the diagnosis of hepatocellular carcinoma. Methods 80 cases of patients with hepatocellular carcinoma admitted to the hospital from April 2016 to April 2018 were enrolled. All patients were given contrast-enhanced ultrasound and CTenhanced scan. The enhancement characteristics, performance characteristics, enhancementpercentage and accuracy were compared betweencontrast-enhanced ultrasound and CT enhanced scan, and theintratumoral vascular morphology and thenecrotic areas morphology were recorded. Results The enhancement characteristics, performance characteristics and enhancement percentage of contrast-enhanced ultrasound and CTenhanced scan were only slightly different (P>0.05). The accuracy of contrast-enhanced ultrasound was higher than that of CTenhanced scan (P<0.05). Conclusion Compared with CT enhanced scan, contrastenhanced ultrasound has the same enhancement mode and enhancementpercentage, but its accuracy is higher.
