A compressed sensing technique was adapted for use in acquiring 3D susceptibility-weighted image data on a clinical 7T MRI system. The image quality was highly dependent on the choice of regularization parameter used in the reconstruction for all accelerated acquisitions, with some residual artifacts manifest in images thought due to the acquisition of anisotropic voxels. Nevertheless, CNR and vein detectability was significantly enhanced in images acquired using the CS-SWI technique compared to the clinical SWI protocol, for CS acceleration factors up to 7.2 (corresponding to a 48% scan time reduction compared to the clinical protocol).
