Reliability of two-dimensional and three-dimensional pseudo-continuous arterial spin labeling perfusion MRI in elderly populations: comparison with 15O-water positron emission tomography.
PURPOSE To investigate the reliability and accuracy of two pseudo-continuous arterial spin labeling (pCASL) sequences, using two-dimensional (2D) gradient-echo echo planar imaging (EPI) and 3D gradient and spin echo (GRASE) as the readout, respectively. MATERIALS AND METHODS Each sequence was performed twice 4 weeks apart on six normal control subjects, six elderly subjects with mild cognitiv...
متن کاملCerebral Blood Flow Imaging with 3D GRASE ASL Sequence Increases SNR and Shortens Acquisition Time
Arterial Spin Labeling (ASL) is a technique capable of measuring cerebral blood flow (CBF) in humans. However, ASL is limited by low sensitivity given blood is ~3% by volume in brain parenchyma. Single-shot 3D GRASE ASL technique has made possible whole brain coverage with over twice the signal-tonoise ratio (SNR) of 2D EPI ASL. To achieve even higher spatial resolution in fast acquisitions, a ...
متن کاملNoise Reduction in Arterial Spin Labeling Based Functional Connectivity Using Nuisance Variables
Arterial Spin Labeling (ASL) perfusion image series have recently been utilized for functional connectivity (FC) analysis in healthy volunteers and children with autism spectrum disorders (ASD). Noise reduction by using nuisance variables has been shown to be necessary to minimize potential confounding effects of head motion and physiological signals on BOLD based FC analysis. The purpose of th...
متن کاملAn improved 3D GRASE pCASL method for whole-brain resting-state functional connectivity
Introduction: Resting-state functional-connectivity (RSFC) has received increasing interest in clinical neuroscience, due to its potential to help translation of fMRI into clinical care [1]. While blood oxygenation level-dependent (BOLD) functional connectivity has been increasing popular, arterial spin labeling (ASL) based functional connectivity has received little attention [2,3]. 3D GRASE (...
متن کاملSub-millimeter T2 weighted fMRI at 7 T: comparison of 3D-GRASE and 2D SE-EPI
Functional magnetic resonance imaging (fMRI) allows studying human brain function non-invasively up to the spatial resolution of cortical columns and layers. Most fMRI acquisitions rely on the blood oxygenation level dependent (BOLD) contrast employing T(*) 2 weighted 2D multi-slice echo-planar imaging (EPI). At ultra-high magnetic field (i.e., 7 T and above), it has been shown experimentally a...
