Agreement of imaging variables measurements between two independent investigators (Intra Class Coefficient or ICC).

	ADC (DWI)	AAR (PWI)	LVu (T2WI)	%HSE (T2WI)	LVc (T2WI)	IS (%AAR)	Infarct growth
mm3	88%	79%	99%	N/A	97%	N/A	80%
%HH (except IS)	89%	76%	99%	96%	96%	92%	N/A

AAR area at risk, ADC apparent diffusion coefficient, DWI diffusion-weighted imaging, IS infarct size, LVc lesion volume corrected, LVu lesion volume uncorrected, N/A non-applicable, PWI perfusion-weighted imaging, T2WI T2-weighted imaging.
