PSMA-targeted therapy is a newer type of radiation therapy that healthcare providers use to treat prostate cancer. Your provider may recommend this treatment if you don’t respond to other prostate cancer treatments or if your prostate cancer spreads to other areas of your body.
How is the Gallium-68 PSMA PET/CT procedure?
The examination needs to be planned a day in advance. Therefore, it is based on an appointment system. The drug is administered intravenously after which there is a waiting period of 45 to 60 minutes. The scanning in the device takes about 20 minutes during which the patient must hold still. A total time to be spent in Nuclear Medicine Department is 2 to 3 hours. Plenty of water is recommended to be drunk before and after the procedure. Patient must stay away from pregnant women and children as radiation will remain for a period of time (8 to 12 hours) after the procedure.
Gallium-68 DOTATATE PET/CT
It is the most advanced technology that may be used in diagnosing neuroendocrine tumours. Neuroendocrine tumour cells have a special receptor called “somatostatin” on their surfaces. DOTATATE is a compound having a structure of peptide that can bound to such receptors. When it is combined with the radioactive agent called “Gallium-68” and administered to the patient, PET/CT device can provide high precision images of the tissues with tumour cells. In this method, patients are not given high doses of radiation.
