NCIt definition : The amino acid analog fluorodopa (FDOPA) labeled with fluorine F 18, a positron-emitting
isotope, with potential tumor tracer property. Fluorine F 18 fluorodopa is able to
cross the blood-brain barrier and is taken up by brain tumor cells. As uptake is higher
in tumor cells, tumors may then be imaged using positron emission tomography (PET).
Assessing tumor uptake of FDOPA may be beneficial for diagnosis, localization and
in determining further treatment.;
