Different segmentation sub compartments of multicentric GBM with multiple bi-cerebral heterogeneously enhancing masses. Top image panel (a–d) shows the pre-segmented, co-registered and skull stripped T1 weighted image (a), T2 weighted image (b), FLAIR image (c), and T1 following IV gadolinium-based contrast administration (d). Bottom image panel (e–h) demonstrates the overlay of the different segmentation labels in respect to the corresponding tumor sub-compartment i.e. enhancing tumor (blue), non-enhancing tumor core (red), surrounding non-enhancing T2/FLAIR hyperintensity (green), and the resection cavity (yellow).
