To compare cerebral blood flow (CBF) and cerebrovascular reserve (CVR) quantification from Turbo-QUASAR (quantitative signal targeting with alternating radiofrequency labeling of arterial regions) arterial spin labeling (ASL) and single post-labeling delay pseudo-continuous ASL (PCASL).

To evaluate the effectiveness of superficial temporal artery-middle cerebral artery (STA-MCA) bypass in improving cerebrovascular reserve (CVR) in Moyamoya syndrome.
What is the topic of this review? This review considers the role of the Na,K-ATPase in cerebrovascular function and how it might be changed in familial hemiplegic migraine type 2 (FHM2). The primary f...
To prospectively evaluate the potential of semi-quantitative evaluation of cerebral perfusion in acute ischemic stroke by comparing two established ultrasound approaches.
The effects of acute mental stress on the mechanisms regulating cerebral blood flow remain unclear. The major novel findings of this study were that: 1) high mental stress and hypercapnia had an inter...
To assess the inter-technique agreement of relative cerebral blood volume (rCBV) measurements obtained using T1- and T2*-perfusion MRI on 3T scanner in glioma patients.
Cerebrovascular reserve (CVR), defined as the increase in cerebral blood flow (CBF)in response to a vasodilatory stimulus, is known to reflect the compensative capacity of the brain to mai...
The purpose of this trial is to study the improvement of cerebral hemodynamics in high risk stroke patients with impaired Cerebrovascular Reserve (CVR) due to high grade stenosis of the in...
Postural changes are commonly used as therapeutic maneuver to enhance or reduce cerebral perfusion. For instance, in acute stroke, the patient can be positioned in head down tilt position ...
The primary aim of this study is to evaluate MRI-based cerebrovascular reserve (CVR) measurements in adult patients with Sickle Cell Disease (SCD). The primary objective is to assess whet...
Coronary artery disease (CAD, coronary heart disease) is the leading cause of death in the U.S., causing 1 in 5 deaths in 2005. The current method for diagnosing coronary artery disease th...
Degeneration of white matter adjacent to the CEREBRAL VENTRICLES following cerebral hypoxia or BRAIN ISCHEMIA in neonates. The condition primarily affects white matter in the perfusion zone between superficial and deep branches of the MIDDLE CEREBRAL ARTERY. Clinical manifestations include VISION DISORDERS; CEREBRAL PALSY; PARAPLEGIA; SEIZURES; and cognitive disorders. (From Adams et al., Principles of Neurology, 6th ed, p1021; Joynt, Clinical Neurology, 1997, Ch4, pp30-1)
A non-invasive technique using ultrasound for the measurement of cerebrovascular hemodynamics, particularly cerebral blood flow velocity and cerebral collateral flow. With a high-intensity, low-frequency pulse probe, the intracranial arteries may be studied transtemporally, transorbitally, or from below the foramen magnum.
An ergot derivative that has been used as a cerebral vasodilator and in peripheral vascular disease. It has been suggested to ameliorate cognitive deficits in cerebrovascular disease.
A calcium channel blockader with preferential cerebrovascular activity. It has marked cerebrovascular dilating effects and lowers blood pressure.
The volume of air contained in the lungs at the end of a maximal inspiration. It is the equivalent to each of the following sums: VITAL CAPACITY plus RESIDUAL VOLUME; INSPIRATORY CAPACITY plus FUNCTIONAL RESIDUAL CAPACITY; TIDAL VOLUME plus INSPIRATORY RESERVE VOLUME plus functional residual capacity; or tidal volume plus inspiratory reserve volume plus EXPIRATORY RESERVE VOLUME plus residual volume.

Radiology is the branch of medicine that studies imaging of the body; X-ray (basic, angiography, barium swallows), ultrasound, MRI, CT and PET. These imaging techniques can be used to diagnose, but also to treat a range of conditions, by allowing visuali...
