Comparison of pulsed and pseudocontinuous arterial spin-labeling for measuring CO2-induced cerebrovascular reactivity

Purpose: To compare the performance of pulsed and pseudocontinuous arterial spin‐labeling (PASL and pCASL) methods in measuring CO2‐induced cerebrovascular reactivity (CVR). Materials and Methods: Subjects were scanned using both ASL sequences during a controlled hypercapnia procedure and visual sti...
