Characterization of flow properties in cerebral arteries with 1.5 and 3 Tesla MRI is usually limited to large cerebral arteries and difficult to evaluate in the small perforating arteries due to insufficient spatial resolution. In this study, we assessed

Multiple blood flow measurements before and after carotid artery stenting via phase-contrast magnetic resonance imaging: An observational study. [PDF]
After carotid artery stenting, the procurement of information about blood flow redistribution among brain-feeding arteries and its time trend is essential to understanding a patient's physiological background and to determine their care regimen. Cerebral

Measuring Pulsatile Flow in Cerebral Arteries Using 4D Phase-Contrast MR Imaging
BACKGROUND AND PURPOSE: 4D PCMRI can be used to quantify pulsatile hemodynamics in multiple cerebral arteries. The aim of this study was to compare 4D PCMRI and 2D PCMRI for assessments of pulsatile hemodynamics in major cerebral arteries.

Variants of cerebral arteries – anterior circulation
Summary Advances in imaging techniques allow for in vivo identification of abnormalities and normal variants of cerebral arteries. These arterial variations can be asymptomatic and uncomplicated although, some of them increase the risk of aneurysm ...

Fetal and Primitive Type of Circle of Willis with Unilateral Trifurcation of Internal Carotid Artery
Circle of Willis is a network of arteries in the base of the brain between the internal carotid artery and the vertebral artery to establish the collateral circulation between these two major arteries.

Blood supply of the internal capsule and basal nuclei [PDF]
The internal capsule and basal nuclei are supplied by perforating branches of the anterior cerebral artery (ACA), Heubner's artery, middle cerebral artery (MCA), internal carotid artery (ICA) and anterior choroidal artery (AChA).

Mitochondrial regulation of NADPH oxidase in hindlimb unweighting rat cerebral arteries.
Exposure to microgravity results in post-flight cardiovascular deconditioning and orthostatic intolerance in astronauts. Vascular oxidative stress injury and mitochondrial dysfunction have been indicated in this process.

Middle cerebral artery Doppler [PDF]
In the last 50 years we have seen tremendous advances in the management of fetal haemolytic anaemia. What was once a disease of high perinatal mortality and morbidity has become a condition readily amenable to antenatal diagnosis and intrauterine fetal therapy.

ABSTRACT Introduction Cognitive impairment and exercise intolerance are common in dialysis patients. Cerebral perfusion and oxygenation play a major role in both cognitive function and exercise execution; HD session per se aggravates cerebral ischemia in this population. This study aimed to compare cerebral oxygenation and perfusion at rest and in mild
