DIVIDE parameter maps from one healthy volunteer in the radiotherapy coil and the head-coil configuration (top two rows) and one patient with a brain metastasis from primary lung cancer (bottom row). The patient row includes a T1-weighted MR image with contrast enhancement from Gadolinium (T1w + C). The gross tumor volume is outlined in red. Abbreviations: mean diffusivity (MD), fractional anisotropy (FA), microscopic fractional anisotropy (µFA), isotropic diffusional variance (MKI), anisotropic diffusional variance (MKA), radiotherapy (RT).
