Clinical study on renalflow perfusion using color Doppler flow imaging combined with quantitative analysistechnique

：Objective To explore theclinical value of color Doppler flow imaging(CDFI) combined with quantitative analysistechnique to evaluate renal flow perflusion. Methods Twenty patients with different renaldiseases matched with healthy control subjects were examined with Philips iU22 CDFIsystem. CDFI system and Qlab quantitative technique were used to measure renal restrictiveindex(RI), vascularization index(VI), flow index(FI), vascularization-flow index (VFI).The patients all received renal single-photon emission computed tomography (SPECT)examination. Results The RI of 32 kidney with lower flow perfusion in SPECT were higherthan in the contol group (P <0.01). VI,FI, VFI were lower than those in control(VI,VFI, P <0.01 ;FI, P <0.05). Conelusious The renal blood flow perfusion of patientswith renal diseases are lower than that of healthy people. It has high clinical valueusing CDFI combined with quantitative analysis technique to evaluate the renal perfusionof the patients with renal diseases.
