PET and CT can be used together to image the physiology and structure of recurrent prostate cancer. Researchers have recently developed PET imaging that focuses on prostate-specific membrane antigen (PSMA). The surface of prostate cancer cells overexpresses PSMA.
PSMA can be detected if the disease spreads to other organs. By administering small doses of gallium-68 (68Ga), a radioactive material, and PSMA-HBED-CC before PET/CT scanning, imaging can detect PSMA with high accuracy. Read more.
