Furthermore, DiffusionKit is a self-contained executable toolkit, without the need to install any other software. It delivers a complete pipeline, including data format conversion, dMRI preprocessing, local reconstruction, white matter fiber tracking, fiber statistical analyses and various visualization schemes. In this work, we developed a light, one-stop, cross-platform solution for dMRI data analysis, called DiffusionKit. However, the existing toolkits for dMRI analysis that have accompanied this surge possess noticeable limitations, such as large installation size, an incomplete pipeline, and a lack of cross-platform support. A sufficiently significant cor- relation of the generalized FA values was not found over the white matter tracts of the olfactory system.ĭiffusion magnetic resonance imaging (dMRI) techniques are receiving increasing attention due to their ability to characterize the arrangement map of white matter in vivo. Results: A significant negative correlation between ADC values and age was obtained. Gen- eralized diffusion parameters such as Fractional Anisotropy (FA) and Apparent Diffusion Coefficient (ADC) of the total tracts of white matter were correlated with age using a Pear- son correlation. The study was conducted with the consent of their parents. Materials and methods: Diffusion tensor imaging was per- formed in fifty-one volunteer children, aged 6-16 years.

The intrinsic trajectories of the olfactory pathway that can be identified using the dif- fusion-weighted magnetic resonance technique provide an important anatomical reference for the evaluation of clinical disorders commonly associated with the olfactory system in the brains of pediatric patients. Diffusion tensor imaging allows virtual dissections of functional white matter tracts in the human brain in vivo using regions of interest (ROI). Introduction: One of the techniques of Nuclear Magnetic Resonance is Diffusion Tensor Imaging, which measures the speed of diffusion of extracellular water molecules found in tissues. Objective: To characterize white matter tracts of the olfac- tory system and evaluate differences in diffusion parameters as a function of age in healthy children. This set of softwares, freely available on-line, offers extra features for further DTI analysis, like volumetric image visualization and fiber bundling. A complementary module called TensorViewer is presented as a nice way to visually inspect the quality of tensor fields produced by DTI Track.

In this tool targeting the clinicians, we offer the full pipeline for DTI analysis, including diffusion tensor estimation, anisotropic tensor smoothing, and fiber tracking.

We show how LE metrics are implemented into a software called MedINRIA, and more especially in a module named DTI Track dedicated to DT-MRI processing. Second, we present the Log-Euclidean (LE) metrics as a more judicious choice as they are less computationally-intensive than the previous one. First, we endow the tensor space with an affine-invariant Riemannian metric and show how some well-known numerical schemes for scalar-or vector-valued images can be adapted to tensors. In this paper, we propose two solutions to tensor computing. Tensors are symmetric, positive definite matrices and suffer from a lack of adapted theoretical tools to manipulate them. The recent emergence of diffusion tensor MRI (DT-MRI) was challenging since data produced by this modality are not simple grey-value images but complex diffusion tensor fields. Major advances in medical imaging raised the need for adapted methods and softwares.
