Comparison of velocity‐selective arterial spin labeling schemes

Magnetic Resonance in Medicine, 2020
In velocity‐selective (VS) arterial spin labeling, strategies using multiple saturation modules or using VS inversion (VSI) pulse can provide improved SNR efficiency compared to the original labeling scheme using one VS saturation (VSS) module.

Determination of spin compartment in arterial spin labeling MRI [PDF]

Magnetic Resonance in Medicine, 2010
AbstractA major difference between arterial‐spin‐labeling MRI and gold‐standard radiotracer blood flow methods is that the compartment localization of the labeled spins in the arterial‐spin‐labeling image is often ambiguous, which may affect the quantification of cerebral blood flow.

Two‐Photon Polymerized Microvascular Environments for Multicellular Modeling of the Blood–Brain Tumor Barrier

Advanced Materials Technologies, EarlyView.
Modeling the blood–brain tumor barrier is challenging due to complex interactions between brain microvasculature and glioma cells. We present two‐photon polymerized 3D micro‐porous capillary‐like structures that support endothelial alignment, cytoskeletal organization, and pericyte‐endothelial‐glioma tri‐cultures.

Quantifying CBF with arterial spin labeling [PDF]

Journal of Magnetic Resonance Imaging, 2005
AbstractThe basic principles of measuring cerebral blood flow (CBF) using arterial spin labeling (ASL) are reviewed. The measurement is modeled by treating the ASL method as a magnetic resonance imaging (MRI) version of a microsphere study, rather than a diffusible tracer study. This approach, particularly when applied to pulsed ASL (PASL) experiments,
