Summary of the QSM and OEF mapping process. The arrows represent the flow of processing. Color coding indicates the use of that information in a particular process (e.g., the R2* map and magnitude images used as morphological priors in MEDI + 0.) QSM, quantitative susceptibility mapping; OEF, oxygen extraction fraction; MEDI + 0, morphology-enabled dipole inversion with an automatic uniform cerebrospinal fluid zero reference algorithm.
