Postictal diffusion changes in the CA1 hippocampal area in patients with a status epilepticus showing a preferential to selective affection of CA1 neurons. Temporal course of the ratio of apparent diffusion coefficient (rADC) changes shows a minimal reduction around days 2 to 3 followed by a normalization to day 10. Post hoc comparisons (t-test) of ADC between time periods show that during all three time points in the acute phase (days 1 to 3) ADC was significantly reduced compared with the normalization phase around day 10. *P<0.05, **P<0.01.
