Diffusion tensor sharpening improves white matter tractography

SPIE Proceedings, 2007
Diffusion Tensor Imaging (DTI) is currently a widespread technique to infer white matter architecture in the human brain. An important application of DTI is to understand the anatomical coupling between functional cortical regions of the brain. To solve this problem, anisotropy maps are insufficient and fiber tracking methods are used to obtain the ...

Diffusion Tensor Imaging and Tractography of Human Brain Development

Neuroimaging Clinics of North America, 2006
Over the past decade, diffusion tensor imaging (DTI) has offered researchers and clinicians a new noninvasive window into the developing human brain, from preterm infants through adolescents and young adults. DTI improves on conventional MR imaging, such as T1-weighted and T2-weighted sequences, through its sensitivity to many microstructural features ...

Diffusion Tensor Tractography of Gliomatosis Cerebri

Journal of Computer Assisted Tomography, 2005
In previous reports, tracts obtained by diffusion tensor (DT) fiber tracking were terminated or deviated by the brain tumors or surrounding edema. There has been no report showing diffusion tensor tractography penetrating through the tumor. A case of glioma is reported, whose DT fiber tract passing through the tumor was observed by changing the ...

Diffusion tensor tractography of the limbic system.

AJNR. American journal of neuroradiology, 2005
The limbic system, relevant to memory and emotion, is an interesting subject of study in healthy and diseased individuals. It consists of a network of gray matter structures interconnected by white matter fibers. Although gray matter components of this system have been studied by using MR imaging, the connecting fibers have not been analyzed to the ...

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 ...

Diffusion tensor imaging and fiber tractography of the normal epididymis

Abdominal Radiology
To evaluate the feasibility of diffusion tensor imaging (DTI) and fiber tractography (FT) of the normal epididymis and to determine normative apparent diffusion coefficient (ADC) and fractional anisotropy (FA) values.Twenty-eight healthy volunteers underwent MRI of the scrotum, including DTI on a 3.0 T system.
