Diffusion Tensor Imaging of Pedophilia
Archives of Sexual Behavior, 2015Pedophilia is a principal motivator of child molestation, incurring great emotional and financial burdens on victims and society. Even among pedophiles who never commit any offense,the condition requires lifelong suppression and control. Previous comparison using voxel-based morphometry (VBM)of MR images from a large sample of pedophiles and controls ...

Diffusion tensor imaging and aging
Neuroscience & Biobehavioral Reviews, 2006Magnetic resonance diffusion tensor imaging (DTI) is a non-invasive in vivo method for characterizing the integrity of anatomical connections and white matter circuitry and provides a quantitative assessment of the brain's white matter microstructure. DTI studies reveal age-related declines in white matter fractional ansiotropy (FA) in normal healthy ...

Diffusion Tensor Imaging in Schizophrenia
Biological Psychiatry, 2005Diffusion tensor imaging (DTI) is a relatively new neuroimaging technique that can be used to examine the microstructure of white matter in vivo. A systematic review of DTI studies in schizophrenia was undertaken to test the hypothesis that DTI can detect white matter differences between schizophrenia patients and normal control subjects.EMBASE, PubMed,

Registration of diffusion tensor images
Proceedings of the 2004 IEEE Computer Society Conference on Computer Vision and Pattern Recognition, 2004. CVPR 2004., 2004This paper presents a novel affine registration algorithm for diffusion tensor images. The proposed metric derived from the standpoint of diffusion profiles not only has concrete physical underpinning but also can be extended for comparing higher-order diffusion models.

, 2019 Regularization of diffusion tensor images
2008 5th IEEE International Symposium on Biomedical Imaging: From Nano to Macro, 2008We present a regularization scheme for diffusion tensor images, that respects the geometrical structure of diffusion ellipsoids and does not introduce artifacts such as anisotropy drops. The method can be stated as a variational problem and solved by means of a gradient flow.

Robust tensor estimation in diffusion tensor imaging
Journal of Magnetic Resonance, 2011The signal response measured in diffusion tensor imaging is subject to detrimental influences caused by noise. Noise fields arise due to various contributions such as thermal and physiological noise and sources related to the hardware imperfection. As a result, diffusion tensors estimated by different linear and non-linear least squares methods in ...

Diffusion Tensor Imaging of Peripheral Nerves
Seminars in Musculoskeletal Radiology, 2015Diffusion tensor imaging (DTI) is a powerful MR imaging technique that can be used to probe the microstructural environment of highly anisotropic tissues such as peripheral nerves. DTI has been used predominantly in the central nervous system, and its application in the peripheral nervous system does pose some challenges related to imaging artifacts ...

Neurology, 2007
It is said that knowledge doubles every 2.5 years. In the field of diagnostic imaging the doubling time is probably shorter due to the rapid pace of technological advances. Diffusion tensor imaging (DTI) and its potential application to neurologic disease represents one such advance.

Diffusion and Diffusion Tensor Imaging in Brain Cancer
Seminars in Radiation Oncology, 2011Conventional magnetic resonance imaging provides important information on the structure of tumors, but new imaging tools are emerging that provide more detailed functional information on tumor biology. In particular, diffusion-weighted imaging (DWI) is sensitive to the tumor microenvironment so it may serve as a prognostic biomarker and an indicator of
