Diffusion Tensor Imaging workflow

About this task

Use these steps to generate parametric images from a Diffusion Tensor data set.
Important: Diffusion Tensor images attempt to characterize behavior of water molecules in imaged tissue. Therefore, fiber tracking representation actually displays algorithmically predicted water molecule direction. These displays may be only representative of the actual white matter anatomy. A trained neuro radiologist is required to make the association between the rendered tract display and the actual patient’s anatomy.

Step-by-step instructions

  1. Open READY View and launch DTI.
    When DTI or DTI Advanced is launched, the system automatically sets the threshold, b-value, and computes the parametric images. The image/graph displayed in each viewport is based on the selected protocol.
  2. Locate the area of interest.
    For details, see Scroll through the images.
  3. Select the desired scan plane and map from the scan plane and map yellow annotation menus.

    • When DTI launches, the default protocol has a particular scan plane and a map(s) displayed in the three map viewports. You may prefer to have a different scan plane and map in each viewport.
    • Right-click the map text in a map viewport to display a different map.
  4. Adjust W/L and mag factor.
