摘　　要：目的：研究英脱利匹特增强超声多普勒血流信号的作用。方法：在１０ 只兔中应用经颅超声多普勒检测静脉推注４ 种不同剂量（０ ．２、０．５、１．０、２．０ｍｌ／ｋｇ）２０ ％ 英脱利匹特前后的动脉血流信号，并以等量的生理盐水作对照。结果：各种剂量２０ ％ 的英脱利匹特注射后多普勒血流信号强度明显增强， 平均比生理盐水及注射前血流信号强度高２６．８±９．７ｄＢ。注射生理盐水后多普勒血流信号强度未见明显改变。结论：静脉注射２０ ％ 英脱利匹特能够增强血流信号，提高多普勒检测的敏感性。Objective This study has investigated the effect of enhancement the intensity of Doppler ultrasound signals of Intralipid. Methods 10 rabbits received four different doses (0.2、0.5、1.0、2.0ml/kg) intravenous injection of 20% Intralipid. The blood flow signals were detected by Transcranial Doppler (TCD) in before and after intravenous injection, The same dosages of saline was injected as control. Results The intensity of Doppler signal increases average 26.8±9.7dB after injection of four different doses 20% Intralipid,while no change after injection saline. Conclusion It was concluded that intravenous injection of 20% Intralipid can enhance Doppler signals and raise the sensitivity of Doppler ultrasound.
