Purpose—The aim of this statement is to review the current data and to make suggestions
for the diagnosis and management of both ruptured and unruptured brain arteriovenous …

Cerebrovascular reactivity (CVR) magnetic resonance imaging (MRI) probes cerebral
haemodynamic changes in response to a vasodilatory stimulus. CVR closely relates to the …

Purpose To evaluate the safety, tolerability, and technical feasibility of mapping
cerebrovascular reactivity (CVR) in a clinical population by using a precise prospectively …

Concussion is a form of traumatic brain injury (TBI) that presents with a wide spectrum of
subjective symptoms and few objective clinical findings. Emerging research suggests that …

Hereditary hemorrhagic telangiectasia (HHT) is a genetic disorder characterized by vessel
dilatation, such as telangiectasia in skin and mucosa and arteriovenous malformations …

Background and Purpose—Increased stroke risk correlates with hemodynamic failure, which
can be assessed with (15O-) H2O positron emission tomography (PET) cerebral blood flow …

Objectives: Brain arteriovenous malformations (AVMs) often present with epileptic seizures,
but prospective data on the risk of seizures with respect to morphologic AVM characteristics …

Attribution of vascular pathophysiology to reductions in cerebrovascular reactivity (CVR) is
confounded by subjective assessment and the normal variation between anatomic regions …

Epilepsy is a chronic neurological disorder generally defined to be caused by excessive
neuronal activity. Thus, excessive neuronal activity is the main target of the currently used …

Respiratory challenge MRI is the modification of arterial oxygen (PaO 2) and/or carbon
dioxide (PaCO 2) concentration to induce a change in cerebral function or metabolism which …
