Abstract
Objective To investigate the value of dynamic imaging on estimating GFR in patients with chronic kidney disease of different stages.Methods Forty-one patients with chronic kidney disease were included. The patients were taken into stage 1 when the GFR was below than 60 ml/(min·1.73 m2) ,and stage 2when the GFR was more than 60 ml/( min·1.73 m2 ) Taking the GFR measured by the duple plasma as the standard, the correlations of GFR measured by renal dynamic imaging and the Cockcroft-Gault formula were analyzed using Pearson correlations analysis. Results The correlation coefficients for dynamic imaging was 0.953(P＜ 0.01 ). The GFR( ml/( min·1.73 m2) obtained by dynamic imaging method and two-sample method was displayed as follows: stage 1 ( 20.62 ± 10.54 ) and ( 26.28 ± 13.1 ); stage2 ( 65.86 ± 20.05 ) and ( 84.70 ±16.89). There was significant difference when dynamic imaging method compared with the two-sample method.Conclusion The dynamic imaging method had a good correlation with the dual plasma sampling method in different stages. There were significant differences when dynamic imaging method compared with GFR-dual plasma sampling method in the full set and in all different stages. Key words: Dynamic imaging; Glomerular filtration rate
