shows the simulation results for the S2 contrast as a function of TR and flip angle α at 7 Tesla. The z-axis shows the BOLD contrast per unit magnetisation [s]. Maximum contrast is achieved for TR = 14 ms and α = 25°.

Activation maps of a single subject of the S2 signal with TR = 15 ms (top), TR = 27 ms (middle), and SE-EPI (bottom) overlaid on the respective mean image. The same colorscale for the z-values ranging from 5.3 to 10 was used for all functional overlays.

Schematic pulse sequence diagram of the proposed FADESS sequence in steady state. TES1 and TES2 denote the echo times of the S1 and S2 signals, respectively. The displacement from the previous (for S1) and next RF pulse (for S2) determines the respective T2* weighting which can be reduced by using an asymmetric readout.
