Comparison of Bone Metastases between ¹⁸F-NaF PET/CT, ¹⁸F-NaF PET, and Planar ^99mTc-MDP Bone Scintigraphy in Patients with Newly Diagnosed Nasopharyngeal Carcinoma

Figure 4

A 31-year-old man with NPC. Planar ^99mTc-MDP bone scintigraphy shows bone metastases in both of the iliac bones (a). ¹⁸F-NaF PET is able to detect more metastatic lesions with significantly better resolution than a conventional bone scan (b). No signs of malignancy were seen in CT (c, d, e). After chemotherapy, follow-up ¹⁸F-NaF PET/CT suggested a disappearance of the lesions, which was confirmed as a true positive ¹⁸F-NaF PET/CT prior to treatment.
