Fig. 3From: The effect of lesion filling on brain network analysis in multiple sclerosis using structural magnetic resonance imagingThe effects of lesion filling on T1w MRI illustrating artefacts due to lesion filling. Red arrows depict the locations of the lesions; blue circles depict lesion filling artefacts. The upper row shows some substantial artefacts due to lesion filling, composed of grey matter tissue allocation in the middle of white matter regions, the lower row shows a minor artefact, having blunt white matter edgesBack to article page
