Skeletal Metastases and Benign Mimics on NaF PET/CT: A Pictorial Review.

ABSTRACT

OBJECTIVE: The aim of this article is to present examples in which sodium fluoride labelled with 18F (NaF) bone PET/CT would be a useful adjunct to guide complex clinical decisions about the staging, restaging, and treatment approach for patients with skeletal metastases and benign causes of NaF activity that can be mistaken for bone metastases. We present a pictorial review of selected cases of this cohort of patients. CONCLUSION: NaF PET/CT hybrid fusion imaging is extremely useful in identifying potential causes of pain in patients with malignancies that have an affinity for skeletal metastases. This technique can help detect bone metastases, in problem solving, and to direct appropriate management.
