- Abstract
An improved arterial spin labeling (ASL) perfusion technique that combines pseudo-continuous labeling and a T2*-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.
