PSMA-PET
Also written as: PSMA-PET — Prostate-Specific Membrane Antigen Positron Emission Tomography
Positron emission tomography imaging using prostate-specific membrane antigen tracers for detecting prostate cancer.
Full Definition
Prostate-specific membrane antigen positron emission tomography is an advanced imaging technique that uses radioactive tracers targeting PSMA, a protein highly expressed on prostate cancer cells. This imaging modality has revolutionized prostate cancer staging and restaging, offering superior sensitivity and specificity compared to conventional imaging. PSMA-PET is particularly valuable for detecting biochemical recurrence, staging high-risk disease, and guiding treatment decisions in metastatic prostate cancer.
Usage
Usage note: Hyphenate PSMA-PET; distinguish from standalone PSMA or PSA.
