  1. 1. Nerve diffusion tensor imaging

    University dissertation from Stockholm : Karolinska Institutet, Dept of Molecular Medicine and Surgery

    Author : Mikael Skorpil; Karolinska Institutet.; Karolinska Institutet.; [2012]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Abstract : Diffusion tensor imaging (DTI) is a magnetic resonance imaging technique that in vivo visualises random translational movement of water molecules. DTI has inherent difficulties with low signal-to-noise ratio, sensitivity to patient motion, field inhomogeneities and fast T2 relaxation. READ MORE

  2. 2. Diffusion tensor magnetic resonance imaging of the brain Tractography analysis with application in healthy individuals and patients

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Johanna Mårtensson; Uppsala universitet.; [2017]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Magnetic Resonance Imaging; Diffusion Tensor Imaging; Tractography; white matter tracts; Radiology; Radiologi;

    Abstract : In study 1, thirty-eight healthy controls were used for optimization of the method. Fifteen patients with progressive supranuclear palsy and an equal number of age-matched healthy controls underwent diffusion tensor MRI and were then investigated and compared groupwise. READ MORE

  3. 3. Computational Diffusion MRI: Optimal Gradient Encoding Schemes

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Mohammad Alipoor; [2016]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Gradient Encoding Scheme; ADC imaging; Diffusion MRI; D-optimal experiment design; Diffusion Tensor Imaging; Optimal Image acquisition; Second and Fourth Order Tensors.; Diffusion Kurtosis Imaging;

    Abstract : Diffusion-weighted magnetic resonance imaging (dMRI) is a non-invasivestructural imaging technique that provides information about tissue microstructures.Quantitative measures derived from dMRI reflect pathologicaland developmental changes in living tissues such as human brain.

  4. 4. Diffusion Tensor Imaging and Tractography in Epilepsy Surgery Candidates

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Daniel Nilsson; Göteborgs universitet.; Gothenburg University.; [2008]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; epilepsy; epilepsy surgery; temporal lobe resection; optic radiation; diffusion tensor imaging; tractography;

    Abstract : In selected patients with medically refractory epilepsy, surgical treatment can render the patients seizure free or significantly reduce seizure frequency. Temporal lobe resection (TLR) for temporal lobe epilepsy (TLE) is the most commonly performed epilepsy surgery procedure. READ MORE

  5. 5. Diffusion Tensor Imaging and Tractography of the Visual Pathways

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Ylva Lilja; Göteborgs universitet.; Gothenburg University.; [2016]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Diffusion tensor imaging; Visual pathways; Tractography; Temporal lobe resection; Pituitary adenomas;

    Abstract : The visual pathways are essential for human vision, stretching from the retinas of the eyes, via the anterior visual pathways and the optic radiations, to the primary visual cortex in the occipital lobe. Injury to these structures will lead to visual impairment – from small deficits to blindness. READ MORE
