Miscellaneous Cancers (Lung, Thyroid, Renal Cancer, Myeloma, and Neuroendocrine Tumors): Role of SPECT and PET in Imaging Bone Metastases
Seminars in Nuclear Medicine, 10/14/09

Chua S et al. – The effectiveness of 18F–FDG–PET is limited in slow–growing tumor types, but 18F–sodium fluoride, a bone radiotracer that can detect early osteoblastic changes, shows promise in this area. Bony metastases from many neuroendocrine tumors can be detected with a high degree of specificity by PET using somatostatin analogs. Other novel and often highly specific radiotracers are under evaluation, which will further enhance the diagnostic capability of PET. The true potential of PET in this group of malignancies is gradually unfolding, although studied series of patients remain generally small and much further evaluation of its role is required.
