Arterial spin labeling perfusion in neonates
Seminars in Fetal and Neonatal Medicine, 2020 Abnormal brain perfusion is a key mechanism underlying neonatal brain injury. Understanding the mechanisms leading to brain perfusion changes in high-risk neonates and how these alterations may influence brain development is key to improve therapeutic strategies preventing brain injury and the neurodevelopmental outcome of these infants.

Arterial Spin-Labeling Perfusion for PHACE Syndrome [PDF]
American Journal of Neuroradiology, 2020 Arterial stroke is a rare-but-reported complication in patients with posterior fossa brain malformations, hemangiomas, arterial anomalies, coarctation of the aorta and cardiac defects, and eye abnormalities (PHACE) syndrome. Currently, stroke risk is inferred by the severity of arterial anomalies identified on MRA, though no evidenced-based data exist.

Myocardial arterial spin labeling [PDF]
Journal of Cardiovascular Magnetic Resonance, 2016 Arterial spin labeling (ASL) is a cardiovascular magnetic resonance (CMR) technique for mapping regional myocardial blood flow. It does not require any contrast agents, is compatible with stress testing, and can be performed repeatedly or even continuously. ASL-CMR has been performed with great success in small-animals, but sensitivity to date has been

Acceleration‐selective arterial spin labeling [PDF]
Magnetic Resonance in Medicine, 2013 In this study, a new arterial spin labeling (ASL) method with spatially nonselective labeling is introduced, based on the acceleration of flowing spins, which is able to image brain perfusion with minimal contamination from venous signal. This method is termed acceleration‐selective ASL (AccASL) and resembles velocity‐selective ASL (VSASL), with the ...

Velocity‐selective arterial spin labeling [PDF]
Magnetic Resonance in Medicine, 2006 Abstract In pathologies in which slow or collateral flow conditions may exist, conventional arterial spin labeling (ASL) methods that apply magnetic tags based on the location of arterial spins may not provide robust measures of cerebral blood flow (CBF), as the transit delay for the delivery of blood to target tissues may far exceed ...

Arterial spin labeling in neuroimaging
World Journal of Radiology, 2010 Arterial spin labeling (ASL) is a magnetic resonance imaging technique for measuring tissue perfusion using a freely diffusible intrinsic tracer. As compared with other perfusion techniques, ASL offers several advantages and is now available for routine clinical practice in many institutions. Its noninvasive nature and ability to quantitatively measure

Modified pulsed continuous arterial spin labeling for labeling of a single artery [PDF]
Magnetic Resonance in Medicine, 2010 AbstractImaging the contribution of different arterial vessels to the blood supply of the brain can potentially guide the treatment of vascular disease and other disorders. Previously available only with catheter angiography, vessel‐selective labeling of arteries has now been demonstrated with pulsed and continuous arterial spin labeling methods ...

Superselective pseudocontinuous arterial spin labeling
Magnetic Resonance in Medicine, 2010 AbstractA new technique for the imaging of flow territories of individual extra‐ and intracranial arteries is presented. The method is based on balanced pseudocontinuous arterial spin labeling but employs additional time‐varying gradients in between the radiofrequency pulses of the long labeling train. The direction of the additional gradient vector is
