General Information About the Test
Test Process and Preparation
Standard imaging methods can miss very small (millimetric) prostate cancer spreads or lymph node metastases. Gallium-68 PSMA, on the other hand, is the method with the highest accuracy and sensitivity (gold standard) because it only finds and attaches to the prostate cancer cell.
The Gallium-68 PSMA radioactive drug is injected intravenously into the patient. The patient is kept waiting in a special room for about 45-60 minutes for the drug to spread throughout the body and bind to the cancer cells. Then, a 20-minute scan is performed in the PET/CT device.
The amount of radioactive material used is extremely low, and the drug has a short half-life. By drinking plenty of water after the procedure, the radiation is quickly excreted from the body via urine. Nevertheless, it is recommended to stay away from pregnant women and small children on the day of the procedure.
