Furthermore, different to 18F-FDG (18F-2-fluoro-2-deoxy-D-glucose fluorodeoxyglucose), similar to the largely used glucose in oncologic molecular imagery, exploration of harmful glioma in 18F-FDOPA, is not compromised by background noise activity, and is almost useless in a healthy cerebral cortex, with the exception of striatal physiological fixation used as a level of reference. The best performances in terms of positive and negative predictive value were defined in the literature with a tumor/striatum threshold of 1.
