BACKGROUND AND PURPOSE: Dizziness is a symptom that develops with internal ear
disturbances and with dysfunctions of the brain stem and cerebellum, in particular with blood …

The aim of this study was to assess blood flow in the middle cerebral artery (MCA) according
to age, gender, and side. Eighty-eight subjects without carotid obstruction were measured …

Objective: A clinically feasible, non-invasive method to quantify blood flow, hemodynamics,
and collateral flow in the vertebrobasilar arterial tree is missing. The objective of this study …

Background and Purpose Flow measurements in the collateral arteries of patients with
internal carotid artery (ICA) occlusions may be important to estimate the risk of future stroke …

Introduction The purpose of the present study was to investigate normal ranges and test-
retest reproducibility of phase-contrast MRI (PC-MRI)-measured flow and velocity …

Background: In vertebrobasilar ischemic stroke, magnetic resonance angiography (MRA)
occasionally fails to visualize the basilar artery, but in these patients, little attention has been …

High-resolution phase—contrast magnetic resonance imaging can now assess flow in
proximal and distal cerebral arteries. The aim of this study was to describe how total cerebral …

BACKGROUND AND PURPOSE: We sought to derive regional cerebral blood flow using
vessel flows from quantitative MR angiography (qMRA). MATERIALS AND METHODS: Flow …

The purpose was to evaluate the blood flow redistribution in the neck vessels of patients with
internal carotid artery (ICA) stenosis. Eighty-six patients with ICA stenosis underwent …

Background and Purpose—In some people the blood supply to the posterior cerebral artery
occurs partly or even exclusively via the carotid system. This anatomic configuration may …
