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.

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 in Brain Tumors.

Journal of computer assisted tomography, 2019
The aim of this review was to review the basic background, technique, and clinical applications of arterial spin labeling in brain tumors. Arterial spin labeling is used for differentiation of brain tumors from nonneoplastic lesions such as infarction ...

Arterial spin labeling: Clinical applications

Journal of Neuroradiology, 2018
Arterial spin labeling (ASL) is a magnetic resonance imaging perfusion technique that enables quantification of cerebral blood flow (CBF) without the use of intravenous gadolinium contrast. An understanding of the technical basis of ASL and physiologic variations in perfusion are important for recognizing normal variants and artifacts.

Arterial Spin Labeling Perfusion Imaging

Magnetic Resonance Imaging Clinics of North America
Noninvasive imaging of tissue perfusion is a valuable tool for both research and clinical applications. Arterial spin labeling (ASL) is a contrast-free perfusion imaging method that enables measuring and quantifying tissue blood flow using MR imaging. ASL uses radiofrequency and magnetic field gradient pulses to label arterial blood water, which then ...

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.

Perfusion Imaging Using Arterial Spin Labeling

Topics in Magnetic Resonance Imaging, 2004
Arterial spin labeling is a magnetic resonance method for the measurement of cerebral blood flow. In its simplest form, the perfusion contrast in the images gathered by this technique comes from the subtraction of two successively acquired images: one with, and one without, proximal labeling of arterial water spins after a small delay time.

Continuous artery‐selective spin labeling (CASSL)

Magnetic Resonance in Medicine, 2005
AbstractA new technique for selective spin labeling of individual arteries is presented. It is based on continuous arterial spin labeling (CASL) with an amplitude‐modulated control experiment. Precessionary motion of the labeling gradient about the axis of the artery, combined with an appropriate frequency modulation of the labeling RF pulse, restricts
