Main results: mean values ± standard deviation (SD) as well as total errors for glomerular filtration rate (GFR) and effective renal plasma flow (ERPF)

	Mean ± SD (min–max)	Total error (%)	r	BA difference
GFR reference value [ml/min]	122 ± 21 (83–167)	12
GFR FDG value (total) [ml/min]	127 ± 28 (83–172)	(11–18)	0.88	− 5 ± 14
GFR FDG value (cortex) [ml/min]	123 ± 33 (75–177)	(16–33)	0.85	− 2 ± 18
ERPF reference value [ml/min]	898 ± 234 (537–1338)	10
ERPF FDG value (total) [ml/min]	858 ± 229 (419–1345)	7	0.82	+ 40 ± 141
ERPF FDG value (cortex) [ml/min]	880 ± 229 (375–1364)	9	0.81	+ 18 ± 143

Ranges from minimum (min) to maximum (max) value are indicated in parentheses. Column 3 presents the Pearson product-moment correlation coefficient r between FDG and reference values and column 4 the differences according to the Bland-Altman (BA) analysis
