Enlarged perivascular spaces in multiple sclerosis on magnetic resonance imaging: a systematic review and meta-analysis. [PDF]

, 2020
BACKGROUND Perivascular spaces can become detectable on magnetic resonance imaging (MRI) upon enlargement, referred to as enlarged perivascular spaces (EPVS) or Virchow-Robin spaces. EPVS have been linked to small vessel disease.

Perivascular network segmentations derived from high-field MRI and their implications for perivascular and parenchymal mass transport in the rat brain

Scientific Reports, 2023
A custom segmentation workflow was applied to ex vivo high-field MR images of rat brains acquired following in vivo intraventricular contrast agent infusion to generate maps of the perivascular spaces (PVS).

Cognitive Impairment in Chronic Kidney Disease Is Associated with Glymphatic System Dysfunction

Kidney Diseases, 2023
Introduction: This study was designed to explore the associations between impaired cognition in chronic kidney disease (CKD) patients and the dysfunction of the glymphatic system. Method: Data were obtained from 77 CKD patients and 50 age-matched healthy

Intensive systolic blood pressure treatment remodels brain perivascular spaces: A secondary analysis of the Systolic Pressure Intervention Trial (SPRINT)

NeuroImage: Clinical, 2023
Highlights • Brain perivascular spaces were segmented in the Systolic Pressure Intervention Trial.• Larger perivascular spaces were associated with older age and cardiovascular disease.• Perivascular space volumes reduced with intensive systolic blood ...

Diffusion along perivascular spaces reveals evidence supportive of glymphatic function impairment in Parkinson disease

Parkinsonism & Related Disorders, 2021
Background: Reduced diffusion along perivascular spaces in adults with Alzheimer’s-disease-related-dementias has been reported and attributed to reduced glymphatic function. Objectives: To apply quantitative measures of diffusion along, and orthogonal to,

The role in thanatogenesis of generalized brain edema in ischemic cerebral infarction (computer-morphometric research)

Patologìâ, 2012
This work presents the results of computer-morphometric study of perivascular and pericellular free (oedematous) spaces in brain cortex at death from the ischemic cerebral infarction and from reasons unconnected directly with cerebral pathology.

Diffusion along perivascular spaces provides evidence interlinking compromised glymphatic function with aging in Parkinson's disease

CNS Neuroscience & Therapeutics, 2022
The aim of the study was to evaluate the glymphatic function and its related factors in patients with Parkinson's disease (PD) and patients with PD of different ages using the diffusion tensor image analysis along the perivascular space (DTI‐ALPS) method.

Giant perivascular spaces: two case reports [PDF]

, 2019
Giant perivascular spaces or Virchow-Robin spaces (VRSs) are uniquely inherent developmental malformation and are generally lined by ependymal or leptomeningeal cells. The cerebral hemispheres with VRSs present multiple cysts of curvilinear, round, oval,
