People or patients with uncontrolled seizure disorder, defined as grand mal (not absence) seizure in the preceding 3 months.\n2. Pregnant females will be excluded. A serum or urine pregnancy test will be administered to all females of child bearing potential within 24 hours of administration of the tracer and MRI scan.

Subjects with typical implanted orthopedic metal in bone may be considered for inclusion in a 7T scan providing the implant is not within the volume of the radio frequency coil. The PI and the AIRC Medical Director will discuss each case and determine eligibility.\n4. Persons with ICD, pacemakers, neurostimulators and other such devices will be excluded.\n5. Persons with claustrophobia are excluded.\n6. Persons with questionable ferrous implants, bullets, BB's, and shrapnel will be excluded.\n7.
