About
The purpose of the study is to learn if Neuraceq™ (Florbetaben F 18 Injection) PET can detect changes in the brains of young athletes who sustained one or more concussions with or without persistent cognitive complaints at least 5 years after injury.
Full description
Former college athletes who sustained at least one previous concussion will undergo computerized neurocognitive testing and a structured questionnaire of present symptoms. [F-18] Florbetaben PET images will be acquired dynamically, with data binned in 20 time frames of 1 min each (early phase), followed by 4 frames of 5 min each (late phase), with image frames summed within each phase after linearly coregistering to subjects' mean images, then elastically transformed to template space of a florbetaben scan used in standardized volume of interest quantification, and intensity normalized to mean voxel value within each phase.
