FIG 5. Temporal evolution of f_fast, ADC_slow (x 10^–3 mm²/s), and ADC_fast (x 10^–3 mm³/s) in patient 8 with ischemic stroke. The maximum decrease in f_fast and the maximum increase in ADC_slow are observed on day 3. An initial increase in both ADC_slow and ADC_fast is observed on days 1 and 3. On day 5, an increase in f_fast is associated with an increase in ADC_fast. This could have been the consequence of rupture of the blood-brain barrier.
