Pilot Prospective Evaluation of (18)F-Alfatide II for Detection of Skeletal Metastases.

ABSTRACT: This pilot prospective evaluation study is to verify the efficiency of (18)F-Alfatide II, a specific PET imaging agent for integrin αvβ3, in detecting bone metastasis in human, with comparison to (18)F-FDG PET. Thirty recruited patients underwent (18)F-FDG and (18)F-alfatide II PET/CT successively within days. The final diagnosis of bone lesions was established based on the comprehensive assessment of all available data and clinical follow-up, which fall into four groups: osteolytic, osteoblastic, mixed and bone marrow. Visual analysis and quantification of SUVmax were performed to compare the detection sensitivity of (18)F-Alfatide II and (18)F-FDG PET. Eleven patients were found to have a total of 126 bone metastasis lesions. (18)F-Alfatide II PET can detect the bone metastatic lesions w
