Leveraging Ellipsoid Bounding Shapes and Fast R-CNN for Enlarged Perivascular Spaces Detection and Segmentation [PDF]

, 2023
Enlarged perivascular spaces (EPVS) are small fluid-filled spaces surrounding blood vessels in the brain. They have been found to be important in the development and progression of cerebrovascular disease, including stroke, dementia, and cerebral small ...

Hemorrhage Pattern and Amyloid Burden in Cerebral Amyloid Angiopathy

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease
Background Cerebral amyloid angiopathy (CAA), a cerebral small vessel disease characterized by vascular amyloid deposition, presents with heterogeneous imaging features, but the biological mechanisms underlying hemorrhagic markers remain unclear.

Giant perivascular spaces: utility of MR in differentiation from other cystic lesions of the brain

Journal of the Belgian Society of Radiology, 2014
Perivascular or Virchow-Robin spaces (VR) of the brain are fluid-filled, pial-lined spaces that accompany the cerebral vessels as they pass from subarachnoid space into the brain parenchyma. They are visualized on routine MR examinations as CSF intensity

Effects of traumatic brain injury on sleep and enlarged perivascular spaces [PDF]

Journal of Cerebral Blood Flow & Metabolism, 2018
Clearance of perivascular wastes in the brain may be critical to the pathogenesis of amyloidopathies. Enlarged perivascular spaces (ePVS) on MRI have also been associated with amyloidopathies, suggesting that there may be a mechanistic link between ePVS and impaired clearance.

Brain Enlarged Perivascular Spaces as Imaging Biomarkers of Cerebrovascular Disease: A Clinical Narrative Review

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2022
: Perivascular spaces or Virchow‐Robin spaces form pathways along the subarachnoid spaces that facilitate the effective clearance of brain metabolic by‐products through intracellular exchange and drainage of cerebrospinal fluid.

Expanding the spectrum of SATB2-associated syndrome: a case with hearing loss and enlarged perivascular spaces

Journal of Pediatric and Neonatal Individualized Medicine
SATB2-associated syndrome (SAS) is a rare neurogenetic disorder char­acterized by intellectual disability, absent or limited speech, craniofacial and dental anomalies, and behavioral disturbances. While most cases are associated with normal hearing, some

Automated Methods for Detecting and Quantitation of Enlarged Perivascular spaces on MRI

Journal of Magnetic Resonance Imaging, 2022
The brain's glymphatic system is a network of intracerebral vessels that function to remove “waste products” such as degraded proteins from the brain. It comprises of the vasculature, perivascular spaces (PVS), and astrocytes. Poor glymphatic function has been implicated in numerous diseases; however, its contribution is still unknown.

Transient but not chronic hyperglycemia accelerates ocular glymphatic transport

Fluids and Barriers of the CNS
Glymphatic transport is vital for the physiological homeostasis of the retina and optic nerve. Pathological alterations of ocular glymphatic fluid transport and enlarged perivascular spaces have been described in glaucomatous mice.

Serum Uric Acid is Independently Associated with Enlarged Perivascular Spaces [PDF]

Scientific Reports, 2017
AbstractEnlarged perivascular spaces (EPVS) are reported to be associated with impaired cognitive function and sleep disorders. It is of clinical importance to understand the risk factors for EPVS. Hyperuricemia increases the risk of hypertension and endothelial dysfunction, which are well recognized to be associated with EPVS. Therefore, we postulated
