Note.— L indicates left; R, right.
* Data are the mean ± SD of the measurements.
^† Error of fit is 0.01 10⁻³ mm²/s. BD_av is the mean of the average diffusion constant distribution measured from the entire brain tissue. σ is the width of this distribution (8).
^‡ Instead of thamali, caudate nuclei were used as control in this patient because TIA involved the right thalamus.
