T1-weighted imaging is a necessary component of clinical brain MR to provide anatomical information at high spatial resolution. T1w brain image in clinical practice is regularly acquired with two-dimensional turbo-spin-echo sequence, which suffers from the pulsation artifacts in the phase-encode direction from superior sagittal sinus, the straight sinus, and the sigmoid sinus. This study exploits the spiral trajectory for the spin-echo sequence to achieve the T1 weighting and to avoid the pulsation artifacts.
