Advanced quantitative susceptibility mapping techniques allow to jointly estimate R2* and QSM in the brain. This work aims at comparing several multi gradient-recalled echo sequences in terms of coil setup and acceleration factors using available product sequences and modern hardware. In addition, an automatic and standardized post-processing pipeline is proposed for clinical studies. We show that quantitative values do not differ from the head coil and acceleration factor that were used, thus allowing for a millimetric whole brain coverage within 5 minutes scan time.
