摘要
目的:评价新型利声显对不同肝肿瘤的彩色多普勒信号和肝实质区回声的增强作用。材料和方法:肝肿瘤患者共44例,其中原发性肝癌35例、继发性肝癌5例、肝血管瘤3例、肝硬化结节1例。使用HP Sonos 2500型彩超仪,控头频率2.5MHz。将利声显稀释为浓度为300mg/ml的溶液,由外周静脉注入,持续观察肿瘤彩色多普勒信号增强程度及肝脏实质区回声。结果:彩色多普勒信号增强情况为:32例原发性肝癌和1例较大胆囊转移癌明显增强,3例原发性小结节型肝癌、4例转移性结节性肝癌、2例肝血管瘤轻度增强,肝硬化结节无增强。肝实质区图像清晰度改善,于4例原发性肝癌患者的肝区内又测及新的小病灶。结论:利声显可增强肝肿瘤的血流信号,且不同肝肿瘤的增强程度有差异。它对判断肿瘤的血供情况、初步分析肿瘤的病理性质,提高超声诊断的敏感性很有益处。
Purpose: To evaluate ultrasound contrast agent, Levovist in enhancing color Doppler singnal of hepatic tumors and parenchyma imaging. Materials and Methods:35 patients with primary hepatocarcinoma (PHC) ,5patients with secondary hepatocarcinoma (SHC), 3cases with hepatic hemangioma, 1 case with cirrhosis node were studied. Levovist 7ml(300/ml) was injected by intravenous and observed enhancing degree of color Doppler singnal inside those tumors and parenchyma imagings.Results;Teh color Doppler singnals in 32patients with PHC and 1 patients with SHC from gall bladder cancer had been enhanced remarkably . Hepatic hemangioma had slight enhanced and cirrhosis node had no enhanced. Meanwhile the parenchyma imaging was improved and small hepatocarcinoma lesions were detected out in 4 patients with PHC. Conclusion: Levovist can enhanced the color Doppler singals of hepatic tumors and there are discrepancy enhancement effects for deflrent tumors. It is beneficial for judging the blood flow condition and pathological nature of the tumors and raisint the sensitivity of ultrasound diagnosis.
