自制脂膜氟烷声学造影剂增强肾脏灰阶显像的实验研究

目的　探讨自制脂膜氟烷声学造影剂“脂氟显”对正常肾灰阶显像的增强效果。方法　 10只健康家兔经耳缘静脉团注 0 .0 1ml/kg的脂氟显 ,采用视觉评分和视频分析 ,观察肾皮质、髓质及肾窦的二维灰阶增强效果。结果　脂氟显不仅能明显增强肾皮质、髓质及肾窦的灰阶显像 ,而且持续时间长 ,肾皮质明显增强时间长达 5 2min ,肾髓质为 2min 2 0s ,肾窦为 1min 40s。结论　脂氟显能长时间显著增强肾脏的灰阶显像

A self-made liposome perfluorocarbon contrast agent enhancing the grey scale of no rmal rabbit kidney: experimental study

Objective To investigate the effect of a self made liposome perfluocarbon ultrasound contrast agent in enhancing grey scale imaging of normal kidney.Methods The kidneys of 10 normal rabbits were imaged with second harmonic imaging before and after intravenous injection of the liposome contrast agent at a dose of 0.01 ml/kg. The subjective scores and video intensities were used to evaluate contrast effects. Results The renal cortex,medulla and sinus grey scale imaging were greatly enhanced after injection, and the notable enhancement time of renal cortex,medulla and sinus could last for 52 min,2 min 20 s,1 min 40 s,respectively. Conclusions The self made liposome perfluocarbon contrast agent can significantly long time enhance the grey scale of the kidney.
