State of the art in nuclear imaging for the diagnosis of bone metastases Place de ?imagerie nucléaire et de ses évolutions pour le diagnostic et le suivi des métastases osseuses

摘要

Cancers prone to spread to bone include prostate, lung, kidney, breast and thyroid cancers. While bone scanner has been widely used in the past decades, PET-based imaging modalities are increasingly used. Current modalities of PET imaging of bone metastases include tumor and inflammatory targeting with FDG-PET, bone imaging with NaF-PET, and direct cancer-specific markers such as FDOPA-PET or PET using choline. The cancer-specific metastatic patterns and the relative prognosis conferred by osseous metastases (versus visceral metastases) may determine the need for bone scan, FDG-PET for the detection of bone metastases. Because some cancers have a mixed skeletal and visceral, cocktails PET radiopharmaceuticals may also be discussed in the future. The cancer-specific context and performances of bone scan and PET imaging are discussed.
