[¹⁸F]FDG-PET of metabolic activity of primary tumors and metastasis of LM2-4 and LM2-4H2N cells.

<p>(A) Representative images of [¹⁸F]FDG uptake in primary tumors of LM2-4 and LM2-4H2N at 11 days post inoculation. Arrows indicate the tumor location. (B) [¹⁸F]FDG uptake in SUV_max for the primary tumor. (C) [¹⁸F]FDG uptake in SUV_max for the muscle. (D) Representative images of [¹⁸F]FDG uptake at different metastatic sites (labelled with arrows) on day 18 post primary tumor removal. (E-F) [¹⁸F]FDG uptake in SUV_max in lung (E) and in metastatic lesions (F) at 18 days post primary tumor removal. (G) Correlation between [¹⁸F]FDG uptake in SUV_max and metastatic nodule volume. L: left. **<i>P</i> < 0.01, ***<i>P</i> < 0.001, Two-way ANOVA/<i>t</i>-test.
