Synopsis

Keywords: Data Acquisition, Pulse Sequence Design, SSFP, susceptibilityThe behaviour of magnetisation under RF spoiling is typically considered to be pseudorandom from TR to TR. Here we describe a model for the coherent underlying phase behaviour which we exploit in a new acquisition strategy. We propose this as an SNR-efficient and motion-robust alternative to multi-echo spoiled gradient echo acquisitions.
