  		FIGURE 1.  Time–activity curves for tracer uptake on 18F-FDOPA PET scans summarized for 11 patients over 75 min from time of injection. (A) Time course of tracer accumulation in tumor tissue, cerebellum, and striatum. Tumor uptake is expressed as mean values of voxels with top 20% SUVs. Error bars denote 1 SE from mean uptake. (B) Time course of tracer accumulation in tumor tissue, cortex, and white matter. Error bars denote 1 SE from mean uptake.

  		FIGURE 4.  (A) Box plots of 18F-FDOPA T/N values in high-grade and low-grade brain tumors and radiation necrosis. There was no statistically significant difference between high-grade and low-grade tumors (P = 0.40). There was a statistically significant difference between tumors and radiation necrosis (P < 0.00001). Error bars indicate SEs. (B) Box plots of 18F-FDOPA T/N values in brain tumors that were contrast enhancing on MRI (CE) and those that did not take up contrast material on MRI (NCE). No statistical difference was seen between CE and NCE tumors (P = 0.40). Statistically significant difference was seen between CE tumors and radiation necrosis (P < 0.00001). Error bars indicate SEs.
