Background: Ischemic stroke is associated with cognitive impairment, but the acute cognitive sequelae of transient ischemic attack (TIA) and minor stroke is unknown. We hypothesized that transient cognitive impairment can be predicted by diffusion-weighted imaging (DWI) lesion volume. Methods:...

High Spatial Resolution Diffusion-Weighted Imaging (DWI) of Ischemic Stroke and Transient Ischemic Attack (TIA)
DownloadFall 2016
Diffusion-weighted imaging (DWI) is the most sensitive imaging technique available to identify ischemic lesions. This magnetic resonance imaging (MRI) technique exploits (non-invasively and in a short scan time) early changes to water mobility caused by metabolic failure of neurons by tagging...
