Purpose
To develop a 2D multi‐echo passband balanced SSFP (bSSFP) sequence using an echo‐train readout with a sequential phase‐encoding order (sequential multi‐echo bSSFP), and evaluate its performance in fast functional brain imaging at 7 T.
Methods
As images of sequential multi‐echo bSSFP exhibit multiple ghosts due to periodic k‐space modulations, a GRAPPA‐based reconstruction method was proposed...
