One of the most common clinical indications for amino acid PET using the tracer -(2-[F]-fluoroethyl)-l-tyrosine (F-FET) is the differentiation of tumor relapse from treatment-related changes in patients with gliomas. A subset of patients may present with an uptake of F-FET close to recommended threshold values. The goal of this study was to investigate the frequency of borderline cases and the role of quantitative F-FET PET parameters in this situation.
