Abstract:
Objective To evaluate the value of the machine-drawn time-intensity curves with intravenous contrast-enhanced color Doppler imaging in study of perfusion of normal kidneys of the rabbits.Methods A series of sequent pictures of 16 normal kidneys of 8 rabbits with color Doppler flow imaging(CDFI) and color Doppler power imaging(CDPI) were collected,and time-intensity curves were drawn by the ultrasound instrument after intravenous administration of "Quanfuxian" contrast medium.Quantitative analyses were done by moving the "interest line".Results The time-intensity curves showed as single apex with steep ascending and slowly descending branch after contrast enhancement.Conclusions The machine-drawn time-intensity curves with intravenous contrast-enhanced color Doppler imaging could efficiently show the perfusion of kidney.
