## Abstract Single shot 3D GRASE is less sensitive to field inhomogeneity and susceptibility effects than gradient echo based fast imaging sequences while preserving the acquisition speed. In this study, a continuous arterial spin labeling (CASL) pulse was added prior to the single shot 3D GRASE re

✦ Synopsis
Abstract
An improved arterial spin labeling (ASL) perfusion technique that combines pseudo‐continuous labeling and a T~2~*‐insensitive sequence (GRASE) with background suppression was used to acquire perfusion maps in normal volunteers and stroke patients. It is shown that perfusion measurements obtained in less than 1 min of scan time are reproducible, with a coefficient of variation of 7%. The perfusion maps generated from these data can be used to characterize the stroke lesion. Magn Reson Med 59:1467–1471, 2008. © 2008 Wiley‐Liss, Inc.
