Figure 5From: Evaluation of the novel folate receptor ligand [18F]fluoro-PEG-folate for macrophage targeting in a rat model of arthritisTissue distribution of [18F]fluoro-PEG-folate. Tissue distribution of [18F]fluoro-PEG-folate in arthritic rats without (black bars) and with (gray bars) pre-treatment with a ≥100-fold molar excess of glucosamine-folate. Results are presented as mean ± SD of four untreated and four pre-treated rats.Back to article page
