Fig 4. A, Graph shows the relation between both CBV and MET uptake ratios and the endothelial cell proliferation. The median values for both CBV and MET uptake ratios were statistically significantly higher in those areas with presence of endothelial cell proliferation (n = 18) compared with the areas without endothelial cell proliferation (n = 47).

B, Graph shows the relation between both CBV and MET uptake ratios and mitotic activity. The median values for both CBV and MET uptake ratios were statistically significantly higher in those areas with presence of mitosis (n = 39) compared with the areas without mitosis (n = 26). Values are presented as minimum-maximum range (whiskers), 25th–75th percentile range (box), and median (open symbols). _**, P = .01; _***, P < .001.
