* Data are the mean ± SD of the measurements.
† Error of fit is 0.01 10−3 mm2/s. BDav 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.
