PET (PSMA) Positron emission tomography with specific prostate marker

Dr. Tomé Lopes, revisto a

This technique consists of performing a PET-CT with the radioactive marker usually used being Gallium (68Ga), or Fluorine (18F), attached to the prostate specific membrane antigen (PSMA).


Thus, it is possible to improve the detection of lesions related to prostate tumors, namely in the characterization of the localized or distant disease, in which ganglionic metastasis is an excellent example.


Its use has been increasing, assuming a great importance in the staging of prostate cancer.
