This work provides novel insights in false positive bundles produced by tractography using a highly realistic diffusion MRI phantom with known underlying white matter ground truth anatomy. This MRI phantom was used in the ISMRM 2015 Tractography Challenge. We show that regardless of the tractography pipeline used, many invalid bundles with dense and meaningful structures are found in the tractograms.
