Until recently, there was no efficacious treatment for acute cerebral ischemia. As a result, the
role of neuroimaging and the radiologist was peripheral in the diagnosis and management …

Magnetic resonance (MR) diffusion imaging allows detection of cerebral ischemia within
minutes of onset, and the temporal evolution of diffusion characteristics enables differentiation …

Background and Purpose— Magnetic resonance imaging (MRI) scans in the elderly commonly
show white matter findings that may raise concerns. We sought to document incidence, …

Background and Purpose— We have previously reported that several “silent” infarcts found
on magnetic resonance imaging (MRI) were a risk factor for stroke. Several recent reports …

Background and Purpose— MRI-defined infarcts are common in the elderly. We sought to
explore incidence, manifestations, and predictors of such infarcts. Methods— The …

Several cerebral pathologic processes thought to result from derangements in vascular
autoregulatory mechanisms show reversible abnormalities on computed tomographic and …

Background: The Cardiovascular Health Cognition Study has evaluated the determinants of
dementia among 3,608 participants that had a magnetic resonance imaging (MRI) of the …

Previously diagnosed diabetes mellitus, newly diagnosed diabetes mellitus, and impaired
glucose tolerance are important determinants of the risk of clinical cardiovascular disease (…

Based on earlier findings that the presence of word comprehension impairment (a deficit in
the meaning of words, or lexical semantics) in acute stroke was strongly associated with the …

Background and Purpose—Cerebral ischemia has been proposed as contributing mechanism
to secondary neuronal injury after intracerebral hemorrhage (ICH). Possible tools for …
