Abstract:
Objective To explore the diagnostic value of whole?body bone scan combined with SPECT/CT imaging for osteofibrous dysplasia( OFD) . Methods A total of 30 patients ( 14 males, 16 fe?males, age range 10-48 ( average age 29.2) years) with OFD confirmed by pathology from June 2007 to De?cember 2014 were included. The images of whole?body bone scan and SPECT/CT imaging were retrospec?tively analyzed. Results Nineteen patients (63.3%, 19/30) showed monostotic OFD, which mainly in?volved extremities (n=18), especially the femur. Eleven patients(36.7%, 11/30) showed polyostotic OFD, which frequently be seen unilaterally (n=7). Highly or obviously abnormal uptakes of radiotracer were shown in most lesions (95.3%, 81/85) on whole?body bone planar images, the ribs and extremities showed abnormal uptake along the backbone orientation, while the cranium, pelvis and spine showed irregu?lar bulky uptake of radioactivity. On SPECT/CT images, the lesions of high or obvious abnormal uptake of radiotracer mainly showed cystic expansion growth, ground glass, vegetable sponge and mixed appearance;and the higher the radioactive aggregation degree was, the more the morphological changes were. The density and morphological changes on CT were not obvious for lesions with moderately and mildly abnormal uptake of radiotracer. Conclusion The whole?body bone scan combined with SPECT/CT imaging is an effective diag?nostic method for OFD.
