摘要
目的 探讨经静脉超声造影对肝肿瘤彩色血流信号的增强作用及其在肿瘤的诊断和鉴别诊断中的应用价值。方法 经外周浅静脉注射声学造影剂后 ,观察 33例肝肿瘤 75个瘤结节造影前、后瘤结节内、外彩色血流增强情况。结果 1 6例原发性肝癌 2 5个瘤结节内及瘤周彩色血流明显增强 ;6例转移性肝癌 2 2个瘤结节内彩色血流无明显增强 ,但瘤周血流增强明显 ;1 1例肝血管瘤 2 8个瘤结节内彩色血流在造影即刻无明显增强 ,延迟显影则有明显增强 ,瘤周血流也增强明显。结论 经静脉超声造影在肝肿瘤的诊断、鉴别诊断及选择治疗措施等方面有重要的临床应用价值。
Objective To study the enhancement of color Doppler signals on hepatic neoplasms with intravenous ultrasound contrast agent and to evaluate the significance in diagnosis of hepatic neoplasms. Methods By injecting contrast agent intravenously, survey color Doppler signals of 75 nodes of neoplasms in 33 cases of hepatic tumor in pre contrast and post contrast. Results The color Doppler signal was obviously enhanced in neoplasms and peri neoplasms(25 nodes) of 16 cases with primary hepatic carcinomas.There was not enhanced in neoplasms(22 nodes) of 6 cases with secondary hepatic carcinomas, but there was a significant enhancement in peri neoplasms. The signal was enhanced in peri neoplasms(28 nodes) of 11 cases with hepatic hemangioma,which came out after injection,but not immediately.Conclusion It plays an important useful role in diagnosis and treatment of hepatic neoplasms to inject ultrasound contrast agent intravenously .
