Venn diagrams showing schematically the overlap between the high metabolic regions (FDG, red), hypoxic regions with a TBR of >1.2 (HX4, green) and increased perfusion blood flow regions (DCE CT, blue) in each patient. The patients are ordered according to the amount of overlap between hypoxia and blood flow. The diagram on the right shows the average overlap volumes for all patients. Venn diagrams for hypoxic regions defined using a TBR of >1.4 are shown in Supplementary Fig. 1
