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

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 ...

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.

Arterial Spin Labeling and Central Precocious Puberty

Clinical Neuroradiology, 2018
To evaluate a non-invasive method to assess the progressivity of idiopathic central precocious puberty (CPP) by quantifying perfusion of the pituitary stalk with arterial spin labeling (ASL) and using the gonadotropin-releasing hormone (GnRH) test as a reference test to define progressive CPP.In a single center retrospective study, 52 consecutive ...

Arterial spin labeling for quantitative functional MRI

The 26th Annual International Conference of the IEEE Engineering in Medicine and Biology Society, 2005
BOLD effect imaging is very effective for detection and localization of brain activity, and is the dominant functional imaging technique in cognitive psychology. Despite its efficiency to detect and localize active site, the technique does not lend itself easily to quantifiable measurements.

Arterial Spin Labeling in Dementia

2017
Arterial spin labeling (ASL) is a type of MR perfusion imaging which utilizes magnetically labeled arterial blood as an intrinsic tracer. Because ASL involves no radioactive tracers or contrast administration, it is considered to be completely noninvasive.
