Using 11C-harmine as tracer for imaging of NET's, tumors in all patients Tumor lesions in all 4 patients with nonfunctioning EPT were clearly visualized by PET (Fig. 9). that the tracer uptake on the PET-scans represent true tumor tissue. PET-positive tumor lesions in 33 out of 36 patients (92 %), a total of 51 Tumors in all patients, but one, did take up this aminoprecursor and could therefore be imaged with PET. When 11C-5-HTP-PET was compared to SRS and CT, more tumor lesions A high 5-HTP uptake was found in the tumor lesions of all patients with a PET-positive tumor lesions in all patients additional value also in PET-imaging of neuroendocrine tumors using tracers variable tracer uptake in different tumor lesions of the same patient. WB-11C-5-HTP-PET has a high tumor detection rate in NET's that ./cache/work_ovznndcq5bddlm7fmvin4ggyzq.pdf ./txt/work_ovznndcq5bddlm7fmvin4ggyzq.txt
