Tyrosine is a natural amino acid and an endogenous substance. 18F-ethyltyrosine (FET) is a tracer that, like amino acids, is taken up by brain tumors and brain metastases, but hardly by normal brain tissue. The tracer is therefore ideally suited for the assessment of brain tumors, metastases and for recurrence diagnostics after therapy. To a certain extent, 18F-FET can also be used to differentiate therapy-induced changes in the brain from tumor recurrence, which is not always possible with other imaging methods.
