[The role of molecular imaging (PET-CT) in the diagnostic and treatment pf prostate cancer].

Prostate cancer is the most frequent cancer type in men in industrialized countries. In case of biochemical recurrent disease of prostate cancer is molecular imaging with PET-CT or PET-MRI a very promising modality for the detection of local recurrence, lymph node involvement or distant metastasis. Of the so far implemented radiopharmaceuticals the radioactive labeled PSMA ligands (i. e. Ga-68 PSMA) have prevailed. There are also in the meanwhile treatment approaches with PSMA ligands (i. e. Lu-177 PSMA) in case of metastatic disease.
