Turbo spin echo (TSE) sequences are useful for rapid, high-resolution structural imaging. However, even small movements during acquisition can cause severe artifacts, due to the motion sensitivity of this technique. This work shows that prospective motion correction can improve results of high resolution TSE imaging even in cooperative volunteers by correcting for position changes between echo trains. When longer readouts are used (e.g. SPACE), a correction once per excitation is not sufficient and continuous correction during the echo train shows further improvement, while preserving the desired sequence timing.
