Overview of the extracted perfusion parameters for the low and high uptake regions inside the primary tumour. P-values are calculated using a paired t-test between low and high FDG-uptake values.

		Low FDG-uptake region (<50% maximum SUV)	High FDG-uptake region (>50% maximum SUV)	low versus high uptake

		mean ± SD	mean ± SD	p-value
Blood Flow [ml/100ml/min]	Maximum slope	39.0 ± 32.3	39.2 ± 20.8	0.961
Blood Flow [ml/100ml/min]	Deconvolution alg.	83.0 ± 62.1	74.6 ± 46.6	0.117
