(a) Qualitative evaluation of automated segmentation in test strains (BXD29M shown) in T1w (21.5 µm voxels) and T2w images (43 µm voxels); (b) Quantitative evaluation of segmentation accuracy, based on 8 labels, for both test strains using T1w, T2w, and a combination of the two channels indicates better performance for T1w and combined T1wT2w channel segmentation in general, with the exception of SN, where T2w provides higher accuracy than T1w (ns).
