摘　　要：目的:应用新型超声造影剂及超声匹配成像新技术,比较彩超及实时灰阶超声造影两种方法对肝占位性病变的应用价值。方法:对35例肝占位性病变总计77个病灶中的42个重点进行造影观察。结果:彩超造影前后血流增强程度评价差异显著(P<0.001);实时灰阶造影结果显示可明显提高肿瘤的定性诊断率(P<0.001)。本组35例造影前为77个病灶,彩超造影后为77个病灶;而实时灰阶造影后共计发现101个病灶,增加24个(23.8%)。结论:彩超造影可以提高肝占位性病变的血流检出率,有助于诊断;实时灰阶造影不仅可对肝占位性病变作出定性诊断,还能提高病灶的检出率。故灰阶超声造影较彩超造影更为重要。Objective: To compare the characteristics of contrast enhanced color DopplerCECD ultrasound with real time contrast enhanced gray scaleCEGS ultrasound in the detection of focal liver lesions by new contrast agent and contrast tissue imaging(CnTI). Materials and Methods: Forty two of 77 various liver lesions in thirty five patients were studied before and after injection of contrast agent. Results: The blood signal between color Doppler ultrasound and CECD was statistically significantP<0.001. The blood signal grade between color Doppler ultrasound and CEGS was statistically significantP<0.001. 77 lesions were found in 35 cases by color Doppler ultrasound or by CECD, but 101 lesions were discovered by CEGS. Conclusion: CECD could improve the demonstration of blood signal in liver focal lesions and improve diagnosis. CEGS not only could distinguish between malignant and benign focal liver lesions, but also improve the detection rate of liver lesions. So CEGS is more important than CECD in clinical application.
