Figure 1: a, c, and f show the lesions (white arrow) and these lesions disappear or resolve partially after thiamine treatment (g-l, white arrows). The ADC map (b) of DWI (a) shows that ADC value in part of the thalamus lesion is reduced (black arrows, b) and nearly normal after treatment (black arrows, h). d and e axially show the elevated CBF in the frontal cortex in the same slice with c and after treatment, the CBF is nearly normal (j and k). a, c, g, and i: axial DWI; b and h: axial ADC; d and j: axial CBF map of PCASL; e: fusion of c and d; f and l: coronal FLAIR; k: fusion of i and j
