http://pipeline.loni.usc.edu/ Splet01. feb. 2014 · MATERIALS AND METHODS: Twenty patients, candidates for excision of epileptogenic lesions, were subjected to higher-angular resolution diffusion imaging–based fiber tractography. Seed points were created without manual bias, predominantly by FreeSurfer and voxel-based atlases. We focused on 2 important fiber bundles, namely the …

Splet01. jun. 2016 · Of the two tractography seeding strategies used, the unidirectional surface-to-surface method, producing dDT1, had a slight performance advantage over the bidirectional voxel-to-surface (dDT3) method. Relative to a geometrically predicted streamline bias, dDT1 showed a bias similar in magnitude, but different in spatial pattern, … SpletSurface seeding is a way to generate initial position for tractography from cortical … tace allen physio

Splet03. okt. 2024 · The presence of drop metastases is the seeding into the subarachnoid space with resultant intradural extramedullary metastases . This has been reported in nearly 30% of the pineal gland tumour cases, with medulloblastoma being the most commonly affected subtype constituting nearly 50% of all cases, followed by ependymomas and … SpletAbstract. We have developed the Tractometer: an online evaluation and validation system … SpletSeeding from voxels within the E-field, voxel-wised connectivity profiles were calculated using Lead-DBS.22 Values in E-fields served as weights to generate the connectivity profile. For each patient, fibres passing through a non-zero voxel of the E-field were selected from the normative connectome and projected onto a voxelised volume in ... tacdis web login
