Gallium 68 PSMA-11
Gallium 68 PSMA-11
Gallium 68 PSMA-11 (pronounced: gal-ee-um 68 P-S-M-A-11), also known as Ga-68 PSMA-11, is a radiopharmaceutical used in Positron Emission Tomography (PET) imaging for the detection of prostate cancer.
Etymology
The term Gallium 68 PSMA-11 is derived from its components. Gallium 68 (Gallium) is a radioactive isotope used as a tracer in medical imaging. PSMA-11 stands for Prostate-Specific Membrane Antigen 11, a type of protein found on the surface of prostate cancer cells.
Usage
Gallium 68 PSMA-11 is used in PET scans to detect and locate prostate cancer in the body. It works by binding to PSMA proteins on the surface of prostate cancer cells, allowing them to be visualized on the PET scan.
