Implication

Combining variable flip angles and k-space filtering optimizes SNR and controls T2 blurring in 3D RARE arterial spin labeling.

Abstract

This work demonstrates that variable flip angles can be derived as the output of an optimization problem. The combined design of variable flip angle and k-space filtering provided superior SNR to designs primarily emphasizing either approach singly.
