Robust method for 3D arterial spin labeling in mice.
Arterial spin labeling is a versatile perfusion quantification methodology, which has the potential to provide accurate characterization of cerebral blood flow (CBF) in mouse models. However, a paucity of physiological data needed for accurate modeling, more stringent requirements for gradient performance, and strong artifacts introduced by magnetization transfer present special challenges for ...
متن کاملRobust Cerebral Blood Flow Map Estimation in Arterial Spin Labeling
Non-invasive measurement of Cerebral Blood Flow (CBF) is now feasible thanks to the introduction of Arterial Spin Labeling (ASL) Magnetic Resonance Imaging (MRI) techniques. To date, the low signalto-noise ratio of ASL gives us no option but to repeat the acquisition in order to accumulate enough data to get a reliable signal. Perfusion signal is usually extracted by averaging across the repeti...
متن کاملMulti-Phase Pseudo-Continuous Arterial Spin Labeling (MP PCASL): Robust PCASL method for CBF quantification
FIG. 3. CBF maps from (a) PCASL and(b) 4-phase PCASL shows overall increase in CBF estimates with 4-phase PCASL. Phase tracking error map (c) show asymmetry of the errors induced at tagging locations. FIG. 4. Comparisons of gray matter CBF (red bar) and SNR efficiency (blue bar) normalized to the values from FAIR ASL. The error bars show the standard deviations. Multi-Phase Pseudo-Continuous Ar...
متن کاملMyocardial arterial spin labeling.
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 poor in large animals and humans and remai...
متن کاملA Method for Automatic Selection of the Labeling Slabs in Regional Arterial Spin Labeling
INTRODUCTION: Arterial Spin Labeling (ASL) is an established technique for non-invasive measurement of cerebral perfusion. In conventional ASL, blood spins of all large feeding arteries are inverted in a slab perpendicular to them to acquire an image of the entire brain perfusion. To visualize the vascular territories of single arteries rather than the whole vascular tree the method of regional...
