Correlation Between Apparent Diffusion Coefficient Values of the Renal Parenchyma and Estimated Glomerular Filtration Rates on 3-T Diffusion-Weighted Echo-Planar Magnetic Resonance Imaging

摘要

Objective To evaluate the relationship between the apparent diffusion coefficient (ADC) values of renal parenchyma and estimated glomerular filtration rates (eGFR). Methods Data on 216 patients examined by 3-T magnetic resonance imaging for various reasons were retrospectively collected. Results There was a significant linear correlation between the ADC values and eGFRs (r = 0.254, P = 60 mL/min per 1.73 m(2)) versus those with a moderate to severe reduction in renal function (eGFR <60 mL/min per 1.73 m(2)).
