This work proposes an automated quantitative evaluation scheme for the GBCA dose reduction using DL.
Overall processing pipeline for the quantitative evaluation scheme. The post-contrast 3D T1W (CE) and DL-CE volumes were skull-stripped, interpolated and co-registered to anatomical template. The volumes are then processed with the BRATS pre-trained volume through the NGC interface to obtain the Tumor Core (TC) segmentation masks.
CE and DL-CE shown side-by-side with the segmented Tumor Core (TC) (green overlay). Individual Dice scores are shown below each image pair. The segmentation mask of DL-CE in image (F) is different from that of CE, even though the enhancement patterns look similar.
