Bone Metastases from Prostate Cancer: 18F-Fluoride PET/CT in a Patient With Discordant Bone Scintigraphy and 11C-Choline PET/CTGarcia, Garzon Jr MD; Riera, Eduard MD; Valls, Eulalia MD; Soler, Marina MD; Bassa, Pere MD; Moragas, Merce MD; Lomeña, Francisco MDClinical Nuclear Medicine: February 2013 - Volume 38 - Issue 2 - p 120–124 doi: 10.1097/RLU.0b013e31827a20d3 Interesting Images Abstract Author Information Abstract: Bone scintigraphy has been used extensively in prostate cancer patients to detect bone involvement. 11C-choline PET/CT is indicated when a biochemical recurrence is suspected, as this procedure is able to detect local recurrence, lymph-node infiltration, and metastases. In cases where the results of these 2 procedures do not coincide, MRI is then usually performed. 18F-fluoride may become an alternative to MRI for bone imaging. In our patient series, all bone lesions with 11C-choline uptake were metastases. 18F-Fluoride did not increase specificity of 11C-choline but increased sensitivity of bone scintigraphy. CT helped in the interpretation of osteoarthritis and trauma lesions. From the Unidad PET/TC CETIR-ERESA, 08950 Esplugues de Llobregat, Barcelona, Spain.
