Association between Perivascular Spaces and Progression of White Matter Hyperintensities in Lacunar Stroke Patients
OBJECTIVES Perivascular spaces are associated with MRI markers of cerebral small vessel disease, including white matter hyperintensities. Although perivascular spaces are considered to be an early MRI marker of cerebral small vessel disease, it is unknown whether they are associated with further progression of MRI markers, especially white matter hyperintensities. We determined the association ...
متن کاملMorphologic, distributional, volumetric, and intensity characterization of periventricular hyperintensities.
BACKGROUND AND PURPOSE White matter hyperintensities are characteristic of old age and identifiable on FLAIR and T2-weighted MR imaging. They are typically separated into periventricular or deep categories. It is unclear whether the innermost segment of periventricular white matter hyperintensities is truly abnormal or is imaging artifacts. MATERIALS AND METHODS We used FLAIR MR imaging from ...
متن کاملTractography at 3T MRI of Corpus Callosum Tracts Crossing White Matter Hyperintensities.
BACKGROUND AND PURPOSE The impact of white matter hyperintensities on the diffusion characteristics of crossing tracts is unclear. This study used quantitative tractography at 3T MR imaging to compare, in the same individuals, the diffusion characteristics of corpus callosum tracts that crossed white matter hyperintensities with the diffusion characteristics of corpus callosum tracts that did n...
متن کاملWhat do white matter hyperintensities really represent?
See related article, pages 600 – 606. W hite matter hyperintensities and small, incidentally found brain infarcts are common findings on MRI, especially in old people, usually regarded as surrogates of small vessel disease. Debette and colleagues have studied the significance of such changes in upper middle-aged persons using the Framingham Offspring cohort. Volumetric brain MRI and neuropsycho...
متن کاملEndothelial function and white matter hyperintensities in older adults with cardiovascular disease.
BACKGROUND AND PURPOSE The presence of white matter hyperintensities on brain MRI is common among elderly individuals. Previous research suggests that cardiovascular risk factors are associated with increased white matter hyperintensities. Examining the role of direct physiological measures of vascular function will help to clarify the vascular mechanisms related to white matter hyperintensitie...
متن کاملBrain white-matter hyperintensities and treatment outcome in major depressive disorder.
BACKGROUND An increased incidence of brain white-matter hyperintensities has been described in major depressive disorder, butthe impact of such hyperintensities on treatment outcome is still controversial. AIMS To investigate the relationship of brain white-matter hyperintensities with cardiovascular risk factors and with treatment outcome in younger people with major depressive disorder. M...
