Abstract

Accelerated GRASE with controlled T2 blurring improves a point spread function (PSF) and temporal signal-to-noise ratio (tSNR) with many slices. The approach seeks to minimize a trade-off between SNR and blurring for functional sensitivity, and uses a new GRASE-optimized random encoding, which takes into accounts for the complex signal decays of T2 and T2* weightings, by achieving incoherent aliasing for constrained reconstruction. Numerical and experimental studies validate the effectiveness of the new method over regular and VFA GRASE (R- and V-GRASE).
