A novel quantitative imaging method based on steady-state signals was proposed to simultaneously resolve MR-related parameters. A special, two-flip angle acquisition was implemented to account for the fluctuations in B1+ field. Furthermore, we developed a motion-resistant sampling scheme to lessen the impact of motion on steady-state signal for in vivo brain scans. A 3D brain imaging that extracts main MR-related parameters such as T1, T2, T2*, M0, B0, and B1+ was performed here in less than 12 minutes.
