Mean ADC values and ratios of ADC ischemic lesions in the core and corresponding contralateral region in acute, subacute, and chronic phases (rADC = ADCI / ADCc)

Time	ADC lesion	ADC contralateral	rADC	P value
< 12 hours	6.32 ± 2.09	10.46 ± 2.30	0.59 ± 0.11	< 0.001
∼ 30 days	10.35 ± 1.99	9.15 ± 0.36	1.12 ± 0.13	0.002
∼ 90 days	13.6 ± 2.22	9.50 ± 1.11	1.48 ± 0.18	0.001

Evolution of ADC characteristics at the core of infarcts; the ADCI (ADC lesion) and ADCc (ADC contralateral region) were compared using two tailed paired t test
