Background and Purpose—In clinical trials and observational studies there is considerable
inconsistency in the use of definitions to describe delayed cerebral ischemia (DCI) after …

An aneurysm is a focal dilatation of an arterial blood vessel. Luminal forces, such as high
blood flow, shear stress and turbulence, are implicated in the pathogenesis of intracranial …

The glymphatic system is a recently discovered network unique to the central nervous system
that allows for dynamic exchange of interstitial fluid (ISF) and cerebrospinal fluid (CSF). As …

Objective: To determine the prevalence and nature of sinovenous obstruction in idiopathic
intracranial hypertension (IIH) using auto-triggered elliptic-centric-ordered three-dimensional …

Background and Purpose— The natural history of aggressive (Borden 2 and 3) cranial dural
arteriovenous fistulas (DAVFs) is not well described. Reported annual mortality and …

Background: Conventional arterial imaging focuses on the vessel lumen but lacks specificity
because different pathologies produce similar luminal defects. Wall imaging can …

Background and Purpose— Patients harboring brain arteriovenous malformations (bAVMs)
are at a lifelong risk for hemorrhagic strokes, but the natural history is poorly understood. We …

Object. Cranial dural arteriovenous fistulas (DAVFs) can be classified into benign or aggressive,

Background and Purpose— In the early 1980s, it was demonstrated that surgical intradural
division of the shunting vein to the medullary venous plexus cures a spinal dural …

Background and Purpose— The correlation between features present in brain arteriovenous
