Susceptibility-related phase contrast associated with the alterations of myelo- architecture in adult-onset leukoencephalopathy with neuroaxonal spheroids and pigmented glia

Abstract

To investigate the origin of susceptibility-weighted imaging (SWI) contrast in frontal white matters of adult-onset leukoencephalopathy with neuroaxonal spheroids and pigmented glia (ALSP), we performed a combined post-mortem magnetic resonance imaging (MRI) and histological study of ALSP pathology. The myelin architectural changes, marked central myelin loss with preserved U-fibers beneath cortical gray matter, mainly contributed to the susceptibility contrast.
