PET/CT Imaging of Prostate Cancer
PET imaging plays a central role in the detection of recurrent prostate carcinoma in the prostate bed and in the differentiation of prostatic from extraprostatic recurrence. Conventional methodology including computed tomography (CT), magnetic resonance imaging (MR), transrectal ultrasound, bone scan and ProstaScint SPECT. Various PET imaging agents have been developed for prostate cancer detection and staging. These include radiolabeled choline, fluorocholine, acetate, minibody, FPA, FDHT, J591, methionine, DCFBC, and etc. FACBC (Axumin, Blue Earth Diagnostics) is indicated for diagnosis of recurrent prostate cancer in men who have elevated blood levels of prostate specific antigen (PSA) after previous treatment, which was originally developed at Emory University and was recently approved by the by the U.S. Food and Drug Administration.
