A, Sagittal T1 FSE (TR, 429 ms; TE, 10 ms; acquisition time, 2 minutes) demonstrates considerable motion artifacts in our patients undergoing mechanical ventilation.B, Sagittal T1 FSE (TR, 429 ms; TE, 10 ms) with the navigator pulse to gate the same as patient's head rocking motion. Although the acquisition time for this sequence was 3.5 minutes, it is still far superior in quality to the original FSE (A). J.D. Barnwell et al.
