经静脉超声造影增强肝肿瘤彩色血流信号的临床研究

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１６例原发性肝癌２５个瘤结节内及瘤周彩色血流明显增强；６例转移性肝癌２２个瘤结节内彩色血流无明显增强，但瘤周血流增强明显；１１例肝血管瘤２８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，

Clinicalstudy of color Doppler signals in hepatic neoplasms enhanced with intravenous ultrasoundcontrast agent

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 .
