In this work, we present a fast and accurate T2 mapping method based on standard multi-echo turbo spin echo sequences (ME-TSE) that are widely available on clinical scanners. Estimation of T2 values is done by a Bloch simulation-based algorithm. As this method can account for stimulated echoes that occur during the echo train within a TSE sequence, its use for sequences with reduced refocusing flip angle is feasible to avoid SAR problems at higher field strength.
