Pseudo-continuous Arterial Spin Labeling at 7T for Human Brain: Estimation and Correction for Off-resonance Effects Using a Prescan
Pseudo-continuous arterial spin labeling (PCASL) can provide best SNR efficiency with a sufficiently long tag at high fields such as 7T, but it is very sensitive to off-resonance fields at the tagging location. Here a robust Prescan procedure is demonstrated to estimate the PCASL RF phase and gradie...
