Abstract
ObjectiveTo synthesize and analyze 18F-prostate specific membrane antigen (PSMA)-1007, followed by its imaging in prostate cancer.
MethodsBased on one-step method, 18F-PSMA-1007 was produced by the CFN-MPS-200 automatic synthesis module and its quality analysis was conducted. 18F-PSMA-1007 PET/CT imaging was performed in a prostate cancer patient (66 years old).
ResultsThe synthesis time of 18F-PSMA-1007 was about 50 min, and the radiochemical yield was (25.0±5.0) % (attenuation correction, n=3). The radiochemical purity was above 99.0% and was above 98.0% after 6 h. The product was colorless transparent solution with pH value of 7.0-7.5, and the specific activity was (410.0±11.0) MBq/ml and the radioactive nuclear purity was above 99.0%. PET/CT imaging in the patient showed that 18F-PSMA-1007 was highly concentrated in prostate cancer with maximum standardized uptake value (SUVmax) of 40.9.
ConclusionBased on CFN-MPS-200 multifunction synthesis module, 18F-PSMA-1007 can be stably synthesized with high radiochemical yield and can be concentrated in prostate cancer.
