Visualization of Cranial Nerves Using High-Definition Fiber Tractography

Neurosurgery, 2016
Recent studies have demonstrated diffusion tensor imaging tractography of cranial nerves (CNs). Spatial and angular resolution, however, is limited with this modality. A substantial improvement in image resolution can be achieved with high-angle diffusion magnetic resonance imaging and atlas-based fiber tracking to provide detailed trajectories of CNs ...

Fiber-distance-based unsupervised clustering of MR tractography data

Journal of Neuroscience Methods, 2019
MR tractography from diffusion tensor imaging provides a non-invasive way to explore white matter pathways in the human brain. However, a challenge to extracting reliable anatomical information from these data is the use of reliable and effective clustering methodologies.

Diffusion tensor imaging and fiber tractography in brain malformations

Pediatric Radiology, 2013
Diffusion tensor imaging (DTI) is an advanced MR technique that provides qualitative and quantitative information about the micro-architecture of white matter. DTI and its post-processing tool fiber tractography (FT) have been increasingly used in the last decade to investigate the microstructural neuroarchitecture of brain malformations.

Straightening the spinal Cord using fibre tractography

2010 IEEE International Symposium on Biomedical Imaging: From Nano to Macro, 2010
Spinal Cord MRI (SC-MRI) is a challenging research field with numerous important clinical and basic research applications. Some of the SC-MRI applications strongly need to deal with a well straightened spinal cord either for appropriate methodological developments, for better visualization or diagnostic purposes.

Diffusion Tensor Imaging and Fiber Tractography in Acute Stroke

Neuroimaging Clinics of North America, 2005
Diffusion tensor imaging (DTI) permits the quantitative evaluation of white matter pathology using measures of diffusion anisotropy. Fiber tractography based on DTI can reveal the three-dimensional white matter connectivity of the human brain. DTI fiber tractography is used to localize stroke lesions in relation to functionally important pathways and ...
