[摘要] 目的 比较原发性肝癌的超声造影和增强CT血流灌注特征及滋养血管显示率，探讨超声造影的临床应用价值。 方法 对21例21个肝癌病灶行超声造影及增强CT检查，比较病灶超声造影及增强CT的增强模式及滋养血管显示率。 结果 肝癌超声造影和增强CT不同时期的增强程度分级比较差异均无统计学意义(P > 0.05)；超声造影和增强CT增强类型(均匀增强与不均匀增强)及增强面积比较差异均无统计学意义(χ2=0.45，P = 0.5；t = 1.64，P = 0.12)。肝癌动脉期供血血管的显示两者比较差异有统计学意义(χ2=4.0，P = 0.04)，超声造影供血血管显示率高于CT，超声造影供血血管显示率86%(18/21)，增强CT供血血管显示率52.3%(11/21)。 结论 肝癌超声造影与增强CT增强表现一致，可很好地反映肿瘤组织血流灌注特点，超声造影对瘤内供血血管的显示优于增强CT。

[Abstract] Objective To compare the perfusion features of hepatocellular carcinoma and display donating blood vessels with contrast-enhanced ultrasound (CEUS) and contrast-enhanced CT (CECT) and evaluate the clinical application value of CEUS. Methods All of 21 patients with 21 lesions had examination of CEUS and CECT. Enhancement patterns and perfusion characters of liver tumors and display donating blood vessels were compared in different phases. Results The enhancement features in different phases of liver carcinoma showed no significant difference between CEUS and CECT (P > 0.05). and the enhancement patterns(homogeneous or inhomogeneous)and enhancement areas of liver carcinoma showed no significant difference between CEUS and CECT (χ2=0.45,P=0.5; t = 1.64, P = 0.12). CEUS and CECT had significant difference in liver carcinoma of in donating blood vessels display(χ2=4.0, P < 0.05). The donating blood vessels was displayed in CEUS higher than CECT. The donating blood vessels was displayed in 86% (18/21) on CEUS and 52.3% (11/21) on CECT. Conclusion The enhancement patterns of m alignant liver tumors on CEUS were consistent with that on CECT, and can reflect the perfusion features of tumors, CEUS is superior to CECT in display donating blood vessels ......
