prostate specific membrane antigen (psma) imaging

PSMA is a protein that is found on the surface of the majority of prostate cancer cells.  The Hopkins team, led by Professor Marty Pomper, has developed a way to detect prostate cancer cells by attaching a molecule that binds to PSMA and then is detected using a PET / CT scan. The PET tracer that is used is F18.  Other centers are also developing imaging techniques that detect PSMA, as well as ways to treat prostate cancer by attaching a radionuclide to the molecule that binds to PSMA.  Dr. Pienta, with his colleagues Dr. Gorin and Dr. Rowe, is currently investigating the utility of PSMA imaging to help physicians make treatment decisions as compared to conventional imaging.

PSMA imaging is still under investigation and is experimental

PSMA imaging is currently only available as part of clinical trials.
