Magnetic resonance imaging of cerebral blood flow in animal stroke models

Brain Circulation, 2016
Perfusion could provide useful information on the metabolic status and functional status of tissues and organs. This review summarizes the most commonly used perfusion measurement methods: Dynamic susceptibility contrast (DSC) and arterial spin labeling (

Pseudocontinuous Arterial Spin Labeling Perfusion Magnetic Resonance Imaging-a Normative Study of Reproducibility in the Human Brain

, 2012
Pseudocontinuous arterial spin labeling (PCASL), a newly proposed perfusion magnetic resonance imaging (MRI) technique, has the potential of providing a better balance between labeling efficiency and signal-to- noise ratio than conventional ASL methods ...

Quantitative myocardial perfusion in mice based on the signal intensity of flow sensitized CMR

Journal of Cardiovascular Magnetic Resonance, 2012
Background In the conventional approach to arterial spin labeling in the rodent heart, the relative difference in the apparent T1 relaxation times corresponding to selective and non-selective inversion is related to perfusion via a two compartment model ...

Unilateral fetal-type circle of Willis anatomy causes right-left asymmetry in cerebral blood flow with pseudo-continuous arterial spin labeling : a limitation of arterial spin labeling-based cerebral blood flow measurements?

, 2016
: The accuracy of cerebral blood flow measurements using pseudo-continuous arterial spin labeling can be affected by vascular factors other than cerebral blood flow, such as flow velocity and arterial transit time.

Arterial spin labeling perfusion MRI: reproducibility & clinical applications [PDF]

, 2012
Arterial Spin Labeling (ASL) is een relatief nieuwe MRI-techniek die de doorbloeding van de hersenen in beeld brengt zonder te hoeven snijden. Anders dan bij andere technieken die de doorbloeding in beeld kunnen brengen, is er bij ASL geen contrastmiddel
