Multi-parametric mapping is often conducted using multiple separate scans, leading to errors in registration and long scan times. Multi-echo complex data was acquired for two flip angles, with a total scan time of 11 minutes at high resolution. Optimized processing allowed for the generation of high resolution qT1, R2*, QSM, SWI and B0 maps in the same space. The use of all echoes in processing, as well as long maximum TE allows for improvements in image quality. Future studies will investigate optimizing phase processing to further improve image quality while decreasing scan time.
