   * **Multi Stack**: With disc disease, extrusions tend to be fairly localized, though in rare cases may extend cranially or caudally and require modification in your planning. Multi Stack is often appropriate and more time efficient for typical cases, especially when assessing a large number of discs and when accounting for the ventral/dorsal curvature of the spine. It is good practice to use 3-7 slices, centered on the disc, for each disc. Where pathology is suspected, it is also good practice to use enough axial slices to extend to the mid-body of the vertebrae above and below the suspected disc extrusion to catch any disc material not well visualized on a sagittal image. On the Multi Stack plan shown below, note the angle required at the LS junction; significant slice overlap will cause artifact, and in some cases may need to be consolidated into a Single Stack.   * **Multi Stack**: With disc disease, extrusions tend to be fairly localized, though in rare cases may extend cranially or caudally and require modification in your planning.

   * **Single Stack**: With spinal cord pathology such as FCE or myelopathy, disc assessment is less important. Single Stack is most appropriate in this situation. It is good practice to acquire the axial stack from 'normal cord' to 'normal cord' if possible.   * **Single Stack**: With spinal cord pathology such as FCE or myelopathy, disc assessment is less important.
