Quantitative imaging at high to ultra-high fields suffers from prominent B1 field inhomogeneities that affect quantification accuracy. Recently, a 3D triple echo steady-state (TESS) approach has been presented that offers fast B1-insensitive T2 quantification. In this work, the sensitivity to subject motion of 3D-TESS is reduced by investigating a rapid 2D technique suited for brain applications. The feasibility and reliability of 2D TESS-T2 relaxometry is demonstrated in human brain scans at high (3 T) and ultra-high (7 T and 9.4 T) fields. The results accentuate the potential of TESS-T2 to act as valuable measure for the detection of brain tissue alterations.
