In this paper we applied a temporal-shift
analysis of the BOLD signal to delineate regions with abnormal perfusion in
patients with chronic steno-occlusive disease of the cerebrovascular system. We
proposed an improved method of analysis based on an iterative approach for the temporal
shift analysis. We further explored the effects of acetazolamide, a
vasodilator, on the assessment of hemodynamic compromise using temporal-shift
analysis and functional connectivity.
