This prospective pilot study is designed to provide preliminary data on the use of Fluorodeoxyglucose Positron Emission Tomography-Magnetic Resonance Imaging (FDG-PET-MRI) in patients with neurofibromatosis-1 (NF1) associated optic glioma and plexiform neurofibroma (PN).

Subjects will undergo FDG-PET-MRI scans in place of standard of care imaging at 0 and 12 months, unless more frequent imaging is clinically indicated. Subjects and their family caregivers will also undergo serial interviews and complete questionnaires related to the psychosocial aspects of NF1.

Primary Outcome Measures:
  • Plexiform Neurofibroma Cohort: Difference in FDG-avidity between progressive and non-progressive lesions [ Time Frame: 12 months ] [ Designated as safety issue: No ]
    Ratios of SUVmax values within a group of patients who all have progressive disease

  • Optic Glioma Patients: Compare FDG-avidity between patients with progressive and non-progressive disease [ Time Frame: 12 months ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Report descriptive statistics for FDG-PET-MRI results [ Time Frame: 0, 12 months ] [ Designated as safety issue: No ]
    SUV max, tumor/brain uptake ratio, tumor/muscle uptake ratio

  • Explore impact of FDG-PET-MRI surveillance on patient and family caregiver uncertainty and psychological distress [ Time Frame: 0, 12 months ] [ Designated as safety issue: No ]
