Fig. 4From: Assessment of 18F-FDG uptake in idiopathic pulmonary fibrosis: influence of lung density changesResidual correlations taking into account the correction for density. Correlation between the SUVmean-corr and the DLCO (a); the oxygen saturation at the end of the 6MWT (b); the difference in oxygen saturation before and after the 6MWT (c); and the GAP score (d). DLCO = carbon monoxide diffusion. SaO2 = oxygen saturationBack to article page
