YR 2016 UL http://jnm.snmjournals.org/content/57/Supplement_3/38S.abstract AB Early diagnosis and adequate staging are crucial for the choice of adequate treatment in prostate cancer (PC). Morphologic and functional imaging modalities, such as CT and MRI, have had limited accuracy in the diagnosis and nodal staging of PC. Molecular PET/CT imaging with 11C- or 18F-choline–labeled derivatives is increasingly being used, but its role in the diagnosis and initial staging of PC is controversial because of limitations in sensitivity and specificity for the detection of primary PC. For T staging, functional MRI is superior to 11C- or 18F-choline PET/CT. For N staging, 11C- or 18F-choline PET/CT can provide potentially useful information that may influence treatment planning. For the detection of bone metastases, 11C- or 18F-choline PET/CT has had promising results; however, in terms of cost-effectiveness, the routine use of 11C- or 18F-choline PET/CT is still debatable. 11C- or 18F-choline PET/CT might be used in high-risk PC before radiation treatment planning, potentially affecting this planning (e.g., regarding dose escalation). This review provides an overview of the diagnostic accuracy and limitations of 11C- or 18F-choline PET/CT in the diagnosis and staging of PC.
