摘要
目的:探讨氟碳声学造影剂对下肢动脉彩色血流信号的增强作用。方法:15例接受造影检查,超声造影剂经左前臂浅静脉弹丸式注射,剂量0.005ml/kg。结果:注射造影剂后下肢动脉彩色血流信号迅速增多、血流束增宽。高峰期持续时间20~30s(平均25±5s),消退期持续时间52~76s,平均61±6s。结论:氟碳声学造影剂能显著增强下肢动脉彩色血流信号,有助于了解深部血管血流状况。
Objective:To investigate the enhancement of color Doppler signals in normal lower limb arteries by perfluorocarbon contrast agent.Method:Fifteen cases were examined.The ultrasound contrast agents were administrated through forearm veins with bolus injection,the dosage was 0.005ml/kg.Result:The color Doppler signals and flow width were all increased in normal lower limb arteries after the contrast agent was admitted.The peak period sustained 20~30s(means 25±5s),the decrease period lasted for 52~76s(means 61±6s).Conclusion:The results suggested perfluorocarbon contrast agent could give rise color Doppler signals in lower limb arteries,and help to show the color Doppler flow of deep vessels in lower limb.
