Triple-echo steady-state (TESS) has so far been investigated mainly as a particular robust and intrinsically B₁-insensitive method for T₂ relaxation time mapping. Here, its potential for fast simultaneous multi-parametric (T₁, T₂, PD, and B₀) mapping of human brain tissues from a single scan is explored. TESS imaging is performed in 2D mode to mitigate motion sensitivity in the brain and accelerated by simultaneous multi-slice (SMS) imaging using CAIPIRINHA to excite two slices simultaneously providing similar SNR in half the acquisition time as compared to sequential single-slice imaging.
