Objective:To compare the clinical value of dynamic contrast-enhanced MRI(DCE-MRI)and single-photon emission computed tomography(SPECT)renal dynamic imaging in the measurement of glomerular filtration rate(GFR)in the evaluation of renal function in renal ***:A total of 70 recipients who underwent renal transplantation in Baogang Hospital of Inner Mongolia from April of 2015 to April of 2018 were selected as research *** was measured in renal transplant recipients by use of DCE-MRI and SPECT(GFR-MRI and GFR-SPECT respectively),and was compared with creatinine clearance rate(Ccr).The safety of contrast media was evaluated in DCE-MRI ***:The bias of GFR-MRI against Ccr value was higher than that of GFR-SPECT against Ccr value,with 30%and 50%accuracy of GFR-MRI higher than that of GFR-SPECT,and the difference was statistically significant(prenal function in renal transplantation by measuring GFR,and it has a high safety.

Vesicoureteral reflux(VUR)is one of the most common urinary tract anomalies in children and causes renal damage and studies focusing on the effect of VUR on renal function are *** recruited 35 primary VUR patients with recurrent urinary tract infection(UTI)and 10 non-VUR patients with recurrent ***-enhanced voiding urosonography(ceVUS)was performed for VUR grading,and renal dynamic imaging was used for evaluating glomerular filtration rate(GFR,mL/min).Standardized GFR(sGFR),namely GFR/BSA(mL·min-1·m-2),was calculated based on the body surface area(BSA).Total sGFR(tsGFR,mL·min-1·m-2)was obtained from the sum of sGFR on the left and right sides of all the *** risk of renal regurgitation was equal in the unilateral reflux *** sGFR of children with grade Ⅳ(45.74±18.05mL·min-1·m-2)and grade V(49.67±23.63mL·min-1·m-2)reflux was significantly lower than that in children with grade Ⅱ(77.69±22.21 mL·min-1·m-2).The renal function compensation of contralateral non-reflux kidney increased in unilateral reflux group,which was higher than that in the control group and level Ⅱ,Ⅳ and Ⅴ of reflux group *** VUR group of the same grade,sGFR decreased with the age at *** unilateral grade V refux group,the tsGFR was lower than that in the unilateral grade I reflux group(133.51±48.21 vs.186.87+53.49mL·min-1·m-2).The patients with VUR of unilateral grade Ⅱ were significantly older than those with VUR of unilateral grades Ⅱ and Ⅳ.This study indicates that severe VUR is significantly associated with decreased renal ***,VUR should be diagnosed early and managed individually.
