Comparison of Bone Metastases between F-NaF PET/CT, F-NaF PET, and Planar Tc-MDP Bone Scintigraphy in Patients with Newly Diagnosed Nasopharyngeal Carcinoma.

Purpose: Our study aims to compare the diagnostic value of F-NaF positron emission tomography-computed tomography (PET/CT), F-NaF PET, and planar Tc-MDP bone scintigraphy for detection of bone metastases in patients with newly diagnosed nasopharyngeal carcinoma (NPC).

Methods: Our study retrospectively analyzed 58 patients with pathologically proven NPC. They all underwent both F-NaF PET/CT and planar Tc-MDP bone scintigraphy within a 7-day interval.
