18 F-NaF PET/CT IMAGING IN FIBROUS DYSPLASIA OF BONE.


ABSTRACT: Fibrous dysplasia (FD) is a mosaic skeletal disorder resulting in fractures, deformity, and functional impairment. Clinical evaluation has been limited by a lack of surrogate endpoints capable of quantitating disease activity. The purpose of this study was to investigate the utility of 18 F-NaF PET/CT imaging in quantifying disease activity in patients with FD. Fifteen consecutively evaluated subjects underwent whole-body 18 F-NaF PET/CT scans, and FD burden was assessed by quantifying FD-related 18 F-NaF activity. 18 F-NaF PET/CT parameters obtained included (i) SUVmax (standardized uptake value [SUV] of the FD lesion with the highest uptake); (ii) SUVmean (average SUV of all 18 F-NaF-positive FD lesions); (iii) total volume of all 18 F-NaF-positive FD lesions (TV); and (iv) total FD lesion activity determined as the product of TV multiplied by SUVmean (TA =? TV ×? SUVmean ) (TA). Skeletal outcomes, functional outcomes, and bone turnover markers were correlated with 18 F-NaF PET/CT parameters. TV and TA of extracranial FD lesions correlated strongly with skeletal outcomes including fractures and surgeries (p values ??0.003). Subjects with impaired ambulation and scoliosis had significantly higher TV and TA values (P
