Amino acid PET imaging improves diagnosis of pediatric glioma

In pediatric patients with suspected neoplastic tissue, PET imaging with the amino acid tracer 18F-FET showed 87% accuracy in differentiating between lesions that were tumors and those that were non-neoplastic, according to a study presented at the SNMMI Annual Meeting. Repeated PET imaging showed 94% accuracy in ruling out tumor progression or residual tumor in a small subgroup, researchers said. "Our findings suggest that in children and young adults, FET PET can add relevant additional clinical information for treatment planning and monitoring when MRI is equivocal," said Dr. Veronika Dunkl of the Institute of Neuroscience and Medicine at Julich Research Centre in Julich, Germany, and colleagues.
