Mechanism of action

Gallium-68 is a positron-emitting radioisotope conjugated to a PSMA-targeting ligand that accumulates in PSMA-expressing prostate cancer cells. When injected intravenously, the radiotracer localizes to primary tumors and metastases, allowing PET imaging to detect and stage prostate cancer with high sensitivity and specificity. This enables clinicians to identify disease burden and guide treatment decisions.
