a, The T2 hyperintense lesion, located at the base of the skull in the temporal lobe, is shown. b–d, Several pathways with anomalies interdigitate in the vicinity of the lesion. Although the inferior fronto-occipital fasciculus (c; IFOF with RISH0 colormap overlayed and the 20 along-tract sections underlayed) signal did not extend beyond the shaded areas (d; ±1 z-score), the proposed anomaly detection framework identified abnormalities in that region (b, pink shaded areas; bold orange line, original tract-profiles; dotted purple line, reconstructed representation learnt from the network). R, right side; L, left side; A, anterior; P, posterior.
