We propose using a gradient readout, fast MRSI acquisition and a support or stand-alone 3D multi-echo, 3-point Dixon GRE scan for MRI scanner and coil quality assurance (QA). The fast MRSI acquisition with the support 3D GRE scan uses the BRAINO phantom, takes less than 10 minutes and could be used for 1 to 3 months QA. A modified (with an increased FOV), stand-alone 3D GRE scan, takes 3-minutes, could be used either with a spherical or cylindrical phantom and is proposed for daily QA, in addition to the manufacturer EPI-based stability scan.
