Correlation coefficients (r) with accompanying significance (p) value

Control ROI correlations	r	p
DSC DT, ASL AAT	0.765	0.0002a
DSC rCBF, ASL CBF	0.561	0.015a
DSC DT, ASL AATVC	0.685	0.0034a
DSC rCBF, ASL CBFVC	−0.003	0.992
DSC MTT, ASL AATVC	0.185	0.493

AAT, arterial arrival time; AAT_VC, arterial arrival time with vascular crusher; ASL, arterial spin labelling; CBF, cerebral blood flow; CBF_VC, cerebral blood flow with vascular crusher; DSC, dynamic susceptibility contrast; DT, delay time; MTT, mean transit time; rCBF, relative cerebral blood flow; ROI, region of interest.

Correlations shown were obtained from the control ROI only, as tumour ROIs did not have any correlations that were significant between the DSC and ASL measures (not shown).
