Respiratory frequency inspecting system of ultrasonic Doppler;
超声多谱勒呼吸频率检测系统的研究
After the rats were induced diabetes with stroptozotocin, the circulatory parameters of the central retinal artery ( CRA ) were measured using color Doppler imaging, including peak systolic velocity ( PSV) , end diastolic velocity ( EDV) , mean velocity (MV) , resistive index (RI) , and pulsitive index (PI).
用链脲佐菌素(STZ)诱导糖尿病模型后,在第12-13周采用彩色多谱勒对各组视网膜中央动脉(CRA)进行血流参数的测量,包括峰值血流速度(PSV)、舒张期最低流速(EDV)、平均血流速度(MV)、阻力指数(RI)和搏动指数(PI)。
Objective To study the image of color Doppler in severe stenosis and occlusion of internal carotid artery.
①目的探讨彩色多谱勒超声诊断颈内动脉重度狭窄及闭塞的声像图表现。
