We test the feasibility of performing motion tracking during T2 preparation (T2 prep) for the purpose of scan time reduction. For demonstration purposes, a single fully balanced readout is inserted in the midpoint between the innermost pair of T2 prep refocusing RFs to acquire a projection of the imaging volume. Preliminary motion phantom study has shown that this technique does indicate motion without visibly disturbing T2 contrast image quality. More elaborate motion readouts that can be inserted into T2 prep and their performance in human warrant further study.
