Fast In Vivo Susceptibility Imaging using Compressed Sensing & Parallel Imaging

Bing Wu¹, Wei Li¹, Chunlei Liu¹

Susceptibility map may be derived from the image phase information, however obtaining the image phase using a 3D SPGR sequence is usually a time consuming process. A novel image reconstruction method is proposed to accelerate the susceptibility imaging by exploiting the complementary properties of compressed sensing and parallel imaging. We show that qualitatively and quantitatively accurate whole brain susceptibility map at 1mm isotropic resolution with a TE of 40ms may be obtained within 8 minutes.
