Spatially‐confined arterial spin‐labeling with FAIR [PDF]
Journal of Magnetic Resonance Imaging, 2005 AbstractPurposeTo investigate the effectiveness of slab‐selective inversion in pulsed arterial spin labeling with body coil excitation as a means to reduce large vessel contamination of the perfusion signal.Materials and MethodsStudies were conducted by varying the tagging width in multislice flow‐sensitive alternating inversion recovery (FAIR) in ...

Pain response measured with arterial spin labeling [PDF]
NMR in Biomedicine, 2013 The majority of functional MRI studies of pain processing in the brain use the blood oxygenation level‐dependent (BOLD) imaging approach. However, the BOLD signal is complex as it depends on simultaneous changes in blood flow, vascular volume and oxygen metabolism.

Arterial spin labeling angiography using a triple inversion recovery prepulse
, 2011 Arterial spin labeling is a well-known noninvasive angiography technique, which does not necessitate the use of a contrast agent. arterial spin labeling is still clinically underused because of several challenges: (1) long scan times because of the need ...

Selective Arterial Spin Labeling
Topics in Magnetic Resonance Imaging, 2016 Knowledge of the distribution of blood flowing from the heart to the brain-feeding arteries is important for the understanding and diagnosis of cerebrovascular diseases. Due to anatomical variations and anomalies within the cerebrovasculature, together with changes caused by various cerebrovascular diseases, there is high variability in the ...

Model-based super-resolution reconstruction for pseudo-continuous Arterial Spin Labeling
NeuroImageArterial spin labeling (ASL) is a promising, non-invasive perfusion magnetic resonance imaging technique for quantifying cerebral blood flow (CBF). Unfortunately, ASL suffers from an inherently low signal-to-noise ratio (SNR) and spatial resolution ...

Clinical utility of arterial spin labeling magnetic resonance imaging in the evaluation of the brain
Journal of Medical Physics, 2023 Introduction: Cerebral blood flow (CBF) is essential for studying the brain in both normal and diseased states. Arterial spin labeling (ASL) is a functional magnetic resonance imaging (MRI) technique that uses arterial water as an endogenous tracer to ...
