Abstract

Pulsed arterial spin labeling magnetic resonance techniques have been developed recently to estimate cerebral blood flow (CBF). Flow-sensitive alternating inversion recovery (FAIR) is one such technique that has been implemented successfully in humans. Un-inverted FAIR (UNFAIR) is an alternative technique in which the now-sensitive image is acquired following Inversion ofall spins outside the slice of interest, and the control image is acquiredwithout any spin labeling, This approach is potentially more efficient than FAIR since the UNFAIR control image is entirely now independent and need only be acquired once, Here, we describe implementation of the sequence on a clinical 1.5 T magnetic resonance system. Both FAIR and UNFAIR perfusion-weighted images were obtained from six normal volunteers, Wash-in/wash-out curves measured in cortical gray and white matter were practically identical for the two techniques, as predicted by our model, (C) 1999 Wiley-Liss, Inc.
