Arterial spin labeling perfusion in neonates

Seminars in Fetal and Neonatal Medicine, 2020
Abnormal brain perfusion is a key mechanism underlying neonatal brain injury. Understanding the mechanisms leading to brain perfusion changes in high-risk neonates and how these alterations may influence brain development is key to improve therapeutic strategies preventing brain injury and the neurodevelopmental outcome of these infants.

Clinical applications of arterial spin labeling

NMR in Biomedicine, 2013
MR arterial spin labeling is primarily applied as a neuroimaging method to measure cerebral blood flow. As this technique becomes more widely available, a basic understanding of the clinical applications is necessary for optimal utilization in the setting of patient care.

Estimation of labeling efficiency in pseudocontinuous arterial spin labeling.

Magnetic resonance in medicine, 2010
Pseudocontinuous arterial spin labeling MRI is a new arterial spin labeling technique that has the potential of combining advantages of continuous arterial spin labeling and pulsed arterial spin labeling. However, unlike continuous arterial spin labeling, the labeling process of pseudocontinuous arterial spin labeling is not strictly an adiabatic ...

Arterial Spin Labeling in Pediatric Neuroimaging

Seminars in Pediatric Neurology, 2020
Perfusion imaging using arterial spin labeling noninvasively evaluates cerebral blood flow utilizing arterial blood water as endogenous tracer. It does not require the need of radiotracer or intravenous contrast and offers unique complimentary information in the imaging of pediatric brain.

Acceleration‐selective arterial spin labeling

Magnetic Resonance in Medicine, 2013
In this study, a new arterial spin labeling (ASL) method with spatially nonselective labeling is introduced, based on the acceleration of flowing spins, which is able to image brain perfusion with minimal contamination from venous signal. This method is termed acceleration‐selective ASL (AccASL) and resembles velocity‐selective ASL (VSASL), with the ...

Quantitative multiple boli arterial spin labeling

Magnetic Resonance Imaging, 2023
The mbASL sequence is a hybrid between PASL and pCASL. It was shown to produce high SNR perfusion data. Quantification is crucial in order to produce accurate mbASL CBF maps. We have shown successful quantification by modifying the Buxton ASL kinetic model, optimising the number of pulses used for inversion and examining the optimal labelling slab ...

Arterial spin labeling: a technical overview

Acta Radiologica, 2018
Arterial spin labeling (ASL) is a non-invasive magnetic resonance imaging perfusion method based on changes in net-magnetization of blood water. The absence of contrast use and ionizing radiation, renders ASL valuable in hyper-acute settings as a monitoring tool for repeated dynamical measurements during and after intervention, and for patients with ...

MR Angiography and Arterial Spin Labelling

2010
MRI offers the ability to visualise and measure blood flow in the human body non-invasively. MR angiography (MRA) provides images of the arterial blood vessels within the body and allows measurement of blood velocities along these arteries. Arterial spin labelling (ASL) is a method for measuring the perfusion of blood into tissue (i.e.
