Choline PET/CT vs. Dual Time Point FDG PET/CT in Prostate Cancer

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 Dual time point FDG PET/CT with current methods for the staging of bone and lymph node metastases in patients with newly diagnosed prostate cancer. Better initial staging will result in better treatment of the individual patient. If we are able to develop a more accurate and non-invasive method of staging patients with undetected metastases on current staging will be spared of the side-effects associated with current treatment and staging- impotence, incontinence, radiation damage, bleeding, infection etc.
