Evaluation of Neuroinflammation in Children With Infantile Spasms


The purpose of this study was to investigate the presence of neuroinflammation in children with infantile spasms using 11C-PK11195 positron emission tomography (PK PET) scan, and its response to ACTH treatment by repeating the PK PET scan after treatment.
