BACKGROUND AND PURPOSE: Large-vessel cerebral blood flow quantification has
emerged as a potential predictor of stroke risk. QMRA uses phase-contrast techniques to …

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

PURPOSE: To assess the utility of magnetic resonance (MR) flow quantification in the
evaluation of suspected carotid artery stenosis. MATERIALS AND METHODS: Fifty-five …

PURPOSE To measure mean blood flow in individual cerebral arteries (carotid, basilar,
anterior cerebral, middle cerebral, and posterior cerebral) using a cine phase contrast MR …

BACKGROUND: Quantitative MRA (qMRA) is a relatively new technique that uses traditional
time-of-flight and phase-contrast MRI to visualize extracranial and intracranial vascular …

✓ Magnetic resonance (MR) angiography offers a safe, noninvasive alternative to
conventional angiography in patients with suspected carotid stenosis; however, it tends to …

Real time MR flow quantification was performed with real time acquisition and evaluation of
motion (RACE) in a rigid phantom under steady flow conditions and in the common carotid …

Background The assessment of carotid artery flow by neurovascular ultrasound (nvUS) can
be complemented by real-time phase-contrast (RT-PC) flow MRI which apart from …

Quantitative, multislice dynamic susceptibility contrast-enhanced MRI perfusion
measurements were used to determine the patterns of cerebral blood flow (CBF), cerebral …

OBJECTIVE. Determination of blood flow volume is useful in assessing ischemic
cerebrovascular disease. We compared the blood flow volume measurement of three …
