Computed tomography of "cystic" intramedullary lesions.

abstract：INTRODUCTION:Type 2 diabetes (DM2) is associated with cognitive decline, but the pathogenesis of this important complication remains unclear. We investigated whether abnormalities in neuronal metabolism or membrane integrity in normal appearing cerebral white matter are associated with cognitive impairment in patients ...
