In this study, we describe prominent perivenular spaces as a sign that is seen on high-
resolution (512× 512) transverse T2-weighted MR images in patients with multiple sclerosis …

Background Magnetic resonance imaging (MRI) can provide in vivo assessment of tissue
damage, allowing evaluation of multiple sclerosis (MS) lesion evolution over time–a …

BACKGROUND AND PURPOSE: The distribution of multiple sclerosis (MS) lesions in the
brain follows a specific pattern, with most lesions in the periventricular regions and in the …

Background and Purpose The purpose of this study was to determine if magnetic resonance
(MR) susceptibility-weighted imaging (SWI) can increase the conspicuity of corticomedullary …

Objectives: Many multiple sclerosis (MS) lesions develop around small veins that are
surrounded by perivenular inflammatory cells, but whether veins in the brains of people with …

BACKGROUND AND PURPOSE: Chronic cerebrospinal venous insufficiency (CCSVI) is a
vascular condition characterized by anomalies of the main extracranial cerebrospinal …

Objectives To review the literature on vascular aspects of multiple sclerosis (MS) specifically
pathological observations of the perivenular distribution of MS lesions and venous …

Background: Virchow-Robin spaces (VRS) are associated with vascular and
neurodegenerative disease. In multiple sclerosis (MS), VRS have been associated with …

BACKGROUND AND PURPOSE: CCSVI hypothesizes an association between impaired
extracranial venous drainage and MS. Published sonographic criteria for CCSVI are …

Purpose The aim of this study was to determine the occurrence and distribution of the
'central vein'sign in white matter lesions on susceptibility-weighted magnetic resonance …
