PSMA (prostate specific membrane antigen) is a smart molecule used in both imaging and treatment of prostate cancer. Gallium is labeled with 68 radioactive element and injected into the patient intravenously, followed by imaging with PET/CT device.
Ga-68-PSMA PET/CT for imaging high-risk prostate cancer, detecting its spread to the body, demonstrating relapse in cases with prostate surgery or post-radiotherapy PSA elevation (biochemical recurrence), Lu-177-PSMA (Lutesium) treatment planning, radiotherapy planning and It is used to evaluate response to treatments.
It is more successful than imaging methods such as ultrasonography, CT, MRI in detecting recurrence and prevalence after treatment.
How is Gallium 68 PSMA applied?

- After the drug is given intravenously, 45-60 minutes. There is a waiting period required for the drug to be distributed throughout the body.
- The shooting time inside the device is about 20 minutes, and you should not move during this time.
