Controlling T2 Blurring in 3D RARE Arterial Spin Labeling Acquisition through Optimal Combination of Variable Flip Angles and k-space Filtering

摘要

PurposeTo improve the SNR efficiency and reduce the T2 blurring of 3D RARE stack-of-spiral arterial spin labeling (ASL) imaging by using variable refocusing flip angles and k-space filtering.
