Model-based analysis of multishell diffusion MR data for tractography: how to get over fitting problems (2012)
Journal Article
Jbabdi, S., Sotiropoulos, S. N., Savio, A. M., Graña, M., & Behrens, T. E. (2012). Model-based analysis of multishell diffusion MR data for tractography: how to get over fitting problems. Magnetic Resonance in Medicine, 68(6), https://doi.org/10.1002/mrm.24204

In this article, we highlight an issue that arises when using multiple b?values in a model?based analysis of diffusion MR data for tractography. The non?monoexponential decay, commonly observed in experimental data, is shown to induce overfitting in...

Ball and rackets: inferring fiber fanning from diffusion-weighted MRI (2012)
Journal Article

A number of methods have been proposed for resolving crossing fibers from diffusion-weighted (DW) MRI. However, other complex fiber geometries have drawn minimal attention. In this study, we focus on fiber orientation dispersion induced by within-vox... Read More about Ball and rackets: inferring fiber fanning from diffusion-weighted MRI.
