This trial is active, not recruiting.

Conditions neurofibromatosis-1, optic glioma, plexiform neurofibroma
Sponsor UNC Lineberger Comprehensive Cancer Center
Start date January 2013
End date November 2014
Trial size 15 participants
Trial identifier NCT01800032, LCCC1222


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.
