Figure 2. — Example of true positive (A), false negative (B) and false positive (C) findings in the institutional/external dataset. Three example MRI studies with axial T1-weighted postcontrast images. (A) HD-BM (orange) shows accurate detection of BM (white arrow) in the right precentral gyrus comparable to the ground-truth (GT) segmentation (green). (B) Missed BM (green) were mostly small or associated with subtle contrast enhancement as shown here in the right parietal lobe (white arrow). (C) False positive findings (orange) were predominantly associated with vascular changes (white arrow; capillary telangiectasia).
