We present a comparative study of 16 fiber tractography
algorithms on a test-retest dataset of 9 healthy
subjects. We evaluate the ability of the tractography
methods to provide reproducible tracts geometries, as
well as to reconstruct subject-specific white matter
anatomy. The dataset consists in 9 healthy subjects,
scanned at three time points separated by a 2 weeks
interval. We reconstructed both left and right
corticospinal tracts. Tractography algorithms were
tested using either their freely available
implementations or in house software. We report
contrasted results across tracking methods.
