Steady‐state free precession for T2* relaxometry: All echoes in every readout with k‐space aliasing

open access: yesMagnetic Resonance in Medicine, Volume 94, Issue 4, Page 1563-1576, October 2025.
Abstract Purpose Multi‐echo gradient echo imaging is useful for a range of applications including relaxometry, susceptibility mapping, and quantifying relative proportions of fat and water. This relies primarily on long‐TR multi‐echo gradient echo sequences (FLASH), which by design isolate one signal component (i.e., echo) at a time per readout.
