Prostate cancer is currently the leading newly diagnosed cancer in the industrialized world. Treatment of prostate cancer is highly dependent on the stage of the disease. Current methods for staging of bone metastases are known to be inaccurate. Staging of lymph nodes requires surgery associated with risk of bleeding etc. Prior studies from our department suggest that PET/CT is useful in staging of bone metastases in patients with prostate cancer. The aim of this study is to compare the usefulness of MeAIB PET/CT with current methods for the staging of bone and lymph node metastases in patients with newly diagnosed prostate cancer.
