The combined use of perfusion imaging (PI) and diffusion-weighted imaging (DWI) is opening a new window into the processes that occur during the first hours of ischemia. DWI detects changes in molecular diffusion associated with cytotoxic edema. PI c

Approximately 20% of female heterozygotes of X-linked adrenoleukodystrophy (X-ALD) develop neurological symptoms clinically resembling those of adrenomyeloneuropathy in men. However, only very few studies have systematically investigated the extent a
