Extreme Speed-Up of Acquisition of Perfusion Time Series by Cycled Arterial Spin Labeling MRI

摘要

Quantitative assessment of haemodynamics by cycled arterial spin labeling (CACL) that distinguishes between blood magnetization tagged by a specific labeling pulse, using a time series acquisition in which all measured data sets are used for reconstruction of each single time step, thereby reducing measurement time while maintaining signal-to-noise ration compared to conventional ASL.
