During practicum on Friday:

Diffusion MRI analysis methods

Differential tractography demonstration

Flowchart

Hands-On: Patients with spinocerebellar ataxia

Longitudinal comparison

1. Download two scan session data of sub-SCA202 at the SCA2 Diffusion Tensor Imaging study
2. Create two SRC files
3. Construct FIB files
4. Export NQA from the follow-up scan
5. Open the FIB file of the baseline and load the NQA with registration.
6. Differential fiber tracking to show the change.

Testing the Results

Practicum assignment: Cross-sectional comparison using Differential tractography

1. Create a connectometry database using control data at the SCA2 Diffusion Tensor Imaging study
2. Generate a subject-matched NQA map at [Step C2a: Modify a Connectometry Database]
   • Documentation
   • Subjects demographics: participants.tsv (need to be modified to keep only values)
3. Open the baseline FIB file of the patient #2 and load the subject-matched NQA using [Slice][Insert MNI image]
4. Differential fiber tracking to show the change.
