Analysis of relationship between perfusion magnetic resonance imaging metrics and EGFRvIII mutation status^a

Perfusion MRI	Mutation absent (n = 47)	Mutation present (n = 18)	p-value
rCBV	3.04 (1.40–6.73)	3.53 (1.57–6.08)	0.19
PSR	0.75 (0.21–1.59)	0.80 (0.46–0.96)	0.57
rPH	2.76 (0.87–8.03)	3.68 (2.10–6.12)	0.03

Values expressed as median (range)

MRI magnetic resonance imaging, rCBV relative cerebral blood volume, PSR percent signal recovery, rPH relative peak height
