Fiber Tractography Techniques

This chapter introduces fiber tractography, a diffusion MRI technique that allows reconstructing the organization of biological tissues characterized by consistently oriented structures, or “fibers.” Examples of fibers are axonal bundles in the brain, or

Two-tensor streamline tractography through white matter intra-voxel fiber crossings:Assessedby fMRI

, 2008
An inherent drawback of the traditional diffusion tensor model is its limited ability to provide detailed information about multidirectional fiber architecture within a voxel.

Effects of fiber properties on shrinkage of fiber/PMMA composite-based bone cements

, 2010
Fiber/polymethylmetacrylate (PMMA) composite bone cements were prepared with various fiber types (polyester and kevlar) in %1, 2 and 3 volumes. The shrinkage of the fiber/PMMA composite patterns were then calculated among 150 days. Results indicated that

Fiber Tractography in Diffusion Tensor Magnetic Resonance Imaging: A Survey and Beyond

, 2005
Diffusion tensor magnetic resonance imaging (DT-MRI) is the first noninvasive in vivo imaging modality with the potential to generate fiber tract trajectories in soft fibrous tissues, such as the brain white matter.

DTI-based fiber tractography: why not?

Diffusion tensor imaging (DTI) has been fundamental in enabling the noninvasive exploration of the brain white matter architecture. However, the use of DTI for tractography remains challenging due to the known limitations of the tensor model in capturing
