Schematic representation of the quantitative multi-parametric mapping workflow with data from a brain tumour patient: the gradient multi-echo phase is unwrapped and separated into field and transceiver (TE = 0) components, from which susceptibility and conductivity maps are reconstructed. The M0-weighted magnitude images are utilised for H2O quantification after a series of corrections including T1, T2* and RF field inhomogeneity bias correction. Moreover, the magnitude profiles additionally serve for the identification of tissue boundaries information required in the reconstruction of conductivity.
