Our novel single-shot T2 mapping framework, integrating ES-GRASE acquisition and parametric mapping, has the following advantages. First, signal contamination of high-order echoes is removed in the propose framework. Second, T₂ relaxation times can be accurately measured by incorporating parallel imaging and multi-echo-pathway signal modeling into the reconstruction procedure.
