Cerebrovascular autoregulation in hypoxia: quantitative insights from arterial spin labeling [PDF]

Frontiers in Neuroscience
Hypoxia, defined as an insufficient oxygen supply relative to metabolic demand, induces a cascade of cerebrovascular and metabolic responses aimed at preserving cerebral homeostasis.

Better performance of cerebral blood volume images synthesized from arterial spin labeling and standard MRI in separating glioblastoma recurrence from treatment response than arterial spin labeling [PDF]

Frontiers in Oncology
Cerebral blood volume (CBV) maps play an important role in the differential diagnosis between glioblastoma recurrence and treatment response. However, it needs high injective velocity.

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

Superselective pseudocontinuous arterial spin labeling [PDF]

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

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 ...

Whole-Cerebrum distortion-free three-dimensional pseudo-continuous arterial spin labeling at 7T

NeuroImage, 2023
Fulfilling potentials of ultrahigh field for pseudo-Continuous Arterial Spin Labeling (pCASL) has been hampered by B1/B0 inhomogeneities that affect pCASL labeling, background suppression (BS), and the readout sequence.
