Arterial Spin Labeling Measurement of Arterial Perfusion Territories Using a Localized Labeling RF Coil
INTRODUCTION Arterial spin labeling (ASL) techniques have proven to be an excellent tool to obtain quantitative maps of perfusion non-invasively [1, 2]. ASL is gaining wide-spread use in clinical applications where, together with other MRI techniques such as angiography (MRA), diffusion-weighted MRI (DWI) and T2weighted MRI, it has proven useful for the diagnosis of a variety of cerebrovascular...
متن کاملRenal Perfusion Imaging using Continuous Arterial Spin Labeling with Separate Labeling and Imaging Coils
Introduction: Assessment of renal perfusion rates can provide important information about kidney function, but also about diseases with pathological perfusion changes, e.g. nephrocalcinosis and renal infarction. To minimize potential risks of nephrotoxicity associated with Gd-based MR perfusion techniques, arterial spin labeling (ASL) is currently being adapted to the kidneys [1-3]. ASL, a meth...
متن کاملBackground suppression in arterial spin labeling MRI with a separate neck labeling coil.
In arterial spin labeling (ASL) MRI to measure cerebral blood flow (CBF), pair-wise subtraction of temporally adjacent non-labeled and labeled images often can not completely cancel the background static tissue signal because of temporally fluctuating physiological noise. While background suppression (BS) by inversion nulling improves CBF temporal stability, imperfect pulses compromise CBF cont...

Delay 2 s Fig. 1. ASL experiment from a volunteer at 1.5T. (a) The imaging slice and labeling slab are depicted by yellow and blue boxes. (b) Fat-saturated SPGR image. Perfusion images are shown in (c-e) for delay times of 1 s, 1.5 s and 2 s. Arteries located close to the skin are depicted well; however, perfusion in glandular tissue is hardly visible. The yellow arrow shows an artery which doe...
متن کاملPerfusion imaging using arterial spin labeling.
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. Over the last decade, the method has moved from the ex...
