MTI of white matter hyperintensities.
The severity of tissue changes associated with incidental white matter hyperintensities (WMH) in the elderly cannot be sufficiently determined by conventional MRI. We, therefore, performed a regional analysis of the magnetization transfer ratio (MTR) maps obtained on a 1.5 T scanner from 198 neurologically asymptomatic participants of the Austrian Stroke Prevention Study (mean age 70, age range...
متن کاملWhite matter hyperintensities in migraine
Case-control studies showed that migraine is associated with ischemic stroke. Studies assessing the prevalence of white matter lesions (WML) in migraine however, reported conflicting results, possibly attributable to selection bias by recruiting only severe cases. We conducted a population-based MRI study of migraineurs with aura (N=161), migraineurs without aura (N=134) and controls (N=140), 3...
متن کاملAnatomical Mapping of White Matter Hyperintensities (WMH)
Background and Purpose—MRI segmentation and mapping techniques were used to assess evidence in support of categorical distinctions between periventricular white matter hyperintensities (PVWMH) and deep WMH (DWMH). Qualitative MRI studies generally identify 2 categories of WMH on the basis of anatomical localization. Separate pathophysiologies and behavioral consequences are often attributed to ...

متن کاملWhite matter hyperintensities and hypobaric exposure.
OBJECTIVE Demonstrate that occupational exposure to nonhypoxic hypobaria is associated with subcortical white matter hyperintensities (WMHs) on fluid-attenuated inversion recovery magnetic resonance imaging (MRI). METHODS Eighty-three altitude chamber personnel (PHY), 105 U-2 pilots (U2P), and 148 age- controlled and health-matched doctorate degree controls (DOC) underwent high-resolution MRI...
