Structural imaging, which should be performed at least once in the diagnostic work up of patients with cognitive impairment, serves to exclude other, potentially treatable, diseases, and to identify specific findings useful in distinguishing different forms of neurodegenerative dementia.

Computer Communications, 1986
Abstract This paper outlines the support for OSI which is offered by the Department of Trade and Industry. These activities are set in the context of the worldwide and European standards development situation. The following activities are described: intercept strategy, support to standard making, implementors groups on OSI standards, conformance ...

DTI Connectivity by Segmentation
2010This paper proposes a new method to compute connectivity information from diffusion weighted images. It is inspired by graph-based approaches to connectivity definition, but formulates the estimation problem in the continuum. In particular, it defines the connectivity through the minimum cut in tensor-weighted space.

Recent advances in biological psychiatry promise to improve our understanding and treatment of mental illness through the development of objective, quantitative biomarkers. Furthermore, psychiatric disorders are increasingly conceptualized in terms of aberrant connectivity, where both brain structure and function are impaired.

A Statistical Framework for DTI Segmentation
3rd IEEE International Symposium on Biomedical Imaging: Macro to Nano, 2006., 2006We address the problem of the segmentation of cerebral white matter structures from diffusion tensor images (DTI). DTI can be estimated from a set of diffusion weighted images and provides tensor-valued images where each voxel is assigned with a 3 /spl times/ 3 symmetric, positive-definite matrix.

Advantages and drawbacks of breast DTI
European Journal of Radiology, 2012In 1965, Stejskal and Tanner developed the pulsed gradient spin echo (PGSE) technique for measuring the diffusion coefficient in solution [1]. The discovery of MRI led to the development of diffusion imaging sequences particularly sequences based on echo planar imaging – EPI that facilitate fast clinical diffusion measurements.

AbstractWhile holding vast potential, diffusion tensor imaging (DTI) with single‐excitation protocols still faces serious challenges. Limited spatial resolution, susceptibility to magnetic field inhomogeneity, and low signal‐to‐noise ratio (SNR) may be considered the most prominent limitations.

Neuropsychiatric applications of DTI – a review
NMR in Biomedicine, 2002AbstractPsychiatric disorders are common throughout the world and are a leading cause of disability. There is a growing appreciation of the importance of connectivity to brain function. Disruption of this connectivity can result in brain dysfunction manifested in impaired cognitive functioning and the development of clinical symptoms.

The development of NMR diffusion imaging and diffusion tensor imaging (DTI) has offered the possibility of studying the porous structures beyond anatomical imaging. In fact, random molecular motions, within tissue components, probe tissue microstructures.
