实时超声造影与编码相位反转技术在肝脏局灶性病变鉴别诊断中的应用

目的:探讨实时超声造影技术在肝脏局灶性病变鉴别诊断中的价值。方法:70例肝脏局灶性病变患者,先行二维与彩色多普勒超声检查,后用编码相位反转技术(CPI)与造影剂SonoVue对局灶性病变(共89个)进行实时造影检查,完全记录整个造影过程,分析造影前后的图像特点。结果:70例肝脏局灶性病变患者,其中原发性肝癌18例、转移性肝癌12例、血管瘤20例、肝局灶性结节样增生5例、非均质脂肪肝8例、肝硬化结节7例。超声造影显示不同病变具有不同的造影增强特点,而且病灶图像清晰。超声造影前30例恶性病变仅20例被明确,经造影后明确诊断达28例。结论:实时超声造影技术对肝脏局灶性病变的鉴别诊断有重要价值。

Application of real-time contrast enhanced ultrasonography under coded phase inversion mode in differentiated diagnosising focal liver lesions

Objective:To investigate the value of real-time contrast-enhanced ultrasonography(CEUS) in differentiated diagnosing focal liver lesions.Methods: Seventy patients with eighty-nine focal liver lesions underwent 2D scan,color-Doppler and real-time Sonovue-enhanced ultrasonography under coded phase inversion mode(CPI).A diagnostic score was given to each lesion before and after contrast injection.Seventy patients were diagnosed pathologically by surgery or needle biopsy. Results: Thirty patients with malignancies,before CEUS,only 20 lesions were definitely or tentatively diagnosed as malignant lesions.After CEUS,28 lesions were correctly diagnosed as malignant.The diagnostic accuracy of CEUS was 94%. Conclusion: Real-time CEUS technique may be an effective and reliable method for assessing focal liver lesions,and may be much valuable for the diagnosis of malignant liver tumor.
