Summary of the relation between ASL CBF and PWI CBF values in gray and white matter (upon normalization of median PWI CBF values to median ASL CBF). The whole brain median CBF was 35.5 ml/100g/min. Column 4 relates to red lines, and column 5 relates to green lines in Fig.1a.

Inter-Vendor Reproducibility of Pseudo-Continuous Arterial Spin Labeling at 3 Tesla
PURPOSE Prior to the implementation of arterial spin labeling (ASL) in clinical multi-center studies, it is important to establish its status quo inter-vendor reproducibility. This study evaluates and compares the intra- and inter-vendor reproducibility of pseudo-continuous ASL (pCASL) as clinically implemented by GE and Philips. MATERIAL AND METHODS 22 healthy volunteers were scanned twice o...
متن کاملPrecision and Accuracy of Arterial Spin Labeling Perfusion MRI in the Pediatric Population
Introduction Arterial Spin Labeling (ASL) provides a noninvasive means for measuring quantitative cerebral blood flow (CBF) without the use of exogenous contrast agents, and is particularly appealing for pediatric populations (1). In neurodevelopmental studies, quantitative CBF can serve as an important marker of cognitive development in normal children as well as aberrant changes in brain func...
متن کاملMulti-vendor reliability of arterial spin labeling perfusion MRI using a near-identical sequence: Implications for multi-center studies
INTRODUCTION A main obstacle that impedes standardized clinical and research applications of arterial spin labeling (ASL), is the substantial differences between the commercial implementations of ASL from major MRI vendors. In this study, we compare a single identical 2D gradient-echo EPI pseudo-continuous ASL (PCASL) sequence implemented on 3T scanners from three vendors (General Electric Heal...
متن کاملComparison of gradient- and spin-echo imaging: CBF, CBV, and MTT measurements by bolus tracking.
The authors measured cerebral blood flow (CBF), cerebral blood volume (CBV), and mean transit time (MTT) in pigs by gadodiamide bolus injections and the bolus tracking technique. Two different pulse sequences were applied and compared: gradient-echo (GE) and spin-echo (SE) echoplanar imaging (EPI). After normalization of CBF and CBV values to the area under the arterial input function (AIF), a ...
متن کاملAssesment of perfusion in glial tumors with arterial spin labeling; comparison with dynamic susceptibility contrast method.
PURPOSE Arterial spin labeling perfusion imaging (ASL-PI) is a non-invasive perfusion imaging method that can be used for evaluation and quantification of cerebral blood flow (CBF). Aim of our study was to evaluating the efficiency of ASL in histopathological grade estimation of glial tumors and comparing findings with dynamic susceptibility contrast perfusion imaging (DSC-PI) method.
