T2-Snapshots imaging with simultaneous multislice TESS acquisition

Single slice triple echo steady-state (TESS) imaging has demonstrated potential for robust highly B1-insensitive T2 relaxometry in the human brain. In this work, a Hadamard-encoding excitation scheme is investigated for fast simultaneous multislice TESS acquisitions. The achieved improvement in the signal-to-noise ratio was invested into a reduction of the overall scan time per slice yielding about 10 sec / slice. As a result, simultaneous multislice TESS imaging is of high interest for accurate T2 quantification in the clinical routine offering full brain coverage within clinically acceptable scan times.
