Abstract
The quantitative parameter was successfully derived from the quantitative bone SPECT/CT images. The aim of this study was to evaluate maximum standardized uptake value (SUV) of normal structures in the head and neck with bone SPECT/CT. Fifty-three patients with jaw lesions (11 chronic osteomyelitis, eight osteoradionecrosis and 34 medication-related osteonecrosis of the jaw) who had bone SPECT/CT were prospectively included. The maximum SUV of normal structures including vertebrae, sternal body, parietal bone and hyoid bone were analysed. Statistical analyses for the maximum SUV were performed by Pearson's rank correlation test. A P value lower than 0.05 was considered statistically significant. The maximum SUVs of vertebrae, sternal body, parietal bone and hyoid bone of all patients were 8.10 ± 3.72, 5.16 ± 2.05, 3.67 ± 1.55 and 1.44 ± 0.56, respectively. Furthermore, the maximum SUV of vertebrae was significantly correlated with that of sternal body (Y = 0.527X + 5.388 (R2 = 0.084, P = 0.035)). Maximum SUV with bone SPECT/CT should be useful for characterization of normal structures in the head and neck. Furthermore, the data reported herein can be used for reference in future studies and in clinical settings for head and neck lesions.
