Banding artifacts are frequently observed in brachial plexus imaging, particularly within the spinal canal, with the balanced FFE sequence (b-FFE) at 3.0T due to increased influence of higher magnetic field inhomogeneity compared with clinical 1.5T. In this work we propose using a RF phase cycling technique with b-FFE (namely b-FFE-XD) to reduce the banding artifacts in clinical. This design RF phase limits the intravoxel dephasing of scan object voxels, therefore the artifacts caused by field inhomogeneity decrease. Meanwhile, the compressed SENSE technique was adopted to reduce the scan time. Results demonstrated successful removal of banding artifacts with the proposed technique.
