A method is presented for measurement of perfusion changes during brain activation using a single-shot pulsed spin labeling technique. By employing a double-inversion labeling strategy, stationary tissue (background) signal was suppressed while minimally affecting perfusion sensitivity. This allowed omission of the otherwise required reference scan, resulting in twofold-improved temporal resolution. The method was applied to vi-sual and motor cortex activation studies in humans, and com-pared to standard FAIR-type perfusion labeling techniques. Ex-periments performed at 1.5T and 3.0T indicate a close to 90% suppression of background signal, at a cost of an 11 % and 9%, respectively, reduction in perfusion signal. Combined with the twofold i...
