Abstract:
Objective To assess the value of quantitative color Doppler sonography in patients with systemic lupus erythematosus (SLE). Methods The right renal in 21 patients with SLE and 22 normal subjects were examined with Philips IU22 ultrasonic diagnostic device. Resistence index (RI) of interlobar artery and interlobular artery were measured with color Doppler sonography, vascularity index (VI), flow index (FI) and vascularization flow index (VFI) which reflecting the renal cortical blood flow were calculated with quantitated analysis software. All the parameters between two groups were compared and analyzed. Results The color signals of renal cortical blood flow in patients with SLE were inferior to those of the normal group, especially in the area near the edge of renal. No statistical difference of RI was found between the two groups (P>0.05), while VI, FI and VFI in SLE group were significantly lower than those of the normal group (VI, VFI, P<0.01, FI, P=0.01). Conclusion Color Doppler sonography combined with blood flow quantitative technique provide a helpful, sensitive and convenient tool to detecte the renal changes in SLE patients.
