Features

  • Measurement of up to 256 directions of diffusion-weighting with up to 16 different b-values. (up to 192 directions for MAGNETOM ESSENZA)
  • Inline processing of the Fractional Anisotropy (FA) maps, ADC maps and trace-weighted images based on the tensor.
  • 3D DTI Tractography data in color overlaid onto the anatomy with the 3D Neuro Task Card allows easy navigation through the brain.

 

Additional Information

In the brain, the axons of neurons form fiber tracts which impose directionality (anisotropy) on measurements of water diffusion. The aggregate diffusion of water within these tracts is quantified at each point by the diffusion tensor. Multiple parameters can be derived from the diffusion tensor, including the trace, ADC (Apparent Diffusion Coefficient), the relative anisotropy, and the fractional anisotropy. These secondary parameters are independent of the frame of reference and are very sensitive to white matter pathology.

DTI (option, prerequisite) has optimized sequences for a complete description of the diffusion properties of the brain within the scope of the tensor diffusion model, both for anisotropic and isotropic diffusion which support excellent evaluation of diseases of the white matter.

DTI Evaluation (option, prerequisite) is a post-processing tool for data obtained by DTI Tractography and allows for quantitative evaluation of the rate and direction of water motion within a voxel, calculation of different diffusion parameters and visualization of colored diffusion tensor imaging maps like the Fractional Anisotropy maps. DTI Evaluation also enables ROI-based evaluation of parameter images.

DTI and DTI Evaluation will help you identify anatomical substructures and with the help of fiber direction maps and fiber tracts (tractography) you will be able to assess the microstructural aspects of the brain lesions.
