  2. Any absolute contraindication to 3 Tesla MRI.
  3. Any absolute contraindication to gadolinium.
  4. Contraindication to lumbar puncture such as severe coagulopathy.
  5. High risk carotid atherosclerotic plaque defined as either greater than 70% stenosis or known high risk plaque features such as intra-plaque hemorrhage.
