A new strategy to acquire Susceptibility Weighted Imaging was proposed with Stack of Spiral trajectories to reduce scan time while maintaining adequate SNR. Spiral encoding offers acceleration in scan speed by six times compared to conventional Cartesian methods, with similar SNR, resolution, and image quality. Due to its improved SNR efficiency, the proposed method has the potential to facilitate lesion detection with higher resolution SWI in a reasonable scan time.
