Synopsis

To improve vascular suppression in 3D brachial plexus MR neurography (MRN) with FSE readouts, 3D directionally-selective crusher gradient technique was implemented. 3D Deep learning reconstruction (DLRecon 3D) with denoising and sharpening properties was applied to improve nerve conspicuity. Preliminary data showed that using both DLRecon 3D reconstruction and 3D crusher gradients resulted in improved image quality, image sharpness, and vascular suppression.
