Abstract

Objective: To evaluate the clinical utility of quantitative values obtained with bone single photon emission computed tomography/computed tomography (SPECT/CT) for primary bone neoplasms.

Subjects and methods: Bone SPECT/CT scans of 23 patients with 19 benign bone neoplasms (5 osteoid osteomas, 4 bone giant cell tumor, 4 osteofibrous dysplasia, 3 intraosseous ganglion, 2 aneurysmal bone cyst, 1 intraosseous hemangioma) and 5 malignant bone neoplasms (2 osteosarcoma, 1 periosteal osteosarcoma, 1 malignancy in bone giant cell tumor, 1 Ewing sarcoma) were retrospectively analyzed with maximum standardized uptake value (SUVmax), peak SUV (SUVpeak), mean SUV (SUVmean), metabolic bone volume (MBV), and total bone uptake (TBU) of primary lesions.

Results: Mean SUVmax of 19 benign and 5 malignant primary bone neoplasms were 6.89±3.26 (range 3.9-15.13) and 10.31±3.19 (5.0-13.45) respectively, with statistically significant difference (P=0.048). Mean SUVpeak of those were 5.87±2.83 (range 3.5-13.63) and 9.18±3.05 (4.09-12.03) respectively, with statistically significant difference (P=0.032). Mean SUVmean of those were 4.43±2.11 (range 2.59-9.37) and 7.13±2.90 (3.3-10.42) respectively, with statistically significant difference (P=0.027). Mean MBV of those were 22.0±30.0 (range 2.47-110.61) and 27.8±39.94 (8.59-99.24) respectively, with no statistically significant difference (P=0.72). Mean TBU of those were 80.64±94.57 (range 10.50-373.57) and 166.60±203.97 (28.68-528.13) respectively, with no statistically significant difference (P=0.17).

Conclusion: Quantitative values obtained with bone SPECT/CT may serve as osteoblastic biomarkers for primary bone neoplasm.
