Abstract |
Purpose: The purpose of this study was to evaluate the usefulness of single photon emission computed
tomography (SPECT) of bone using Tc-99m MDP in the diagnosis of osteoporotic vertebral fractures. Materials and
Methods: Thirty two patients with osteoporotic vertebral fracture were included in this study (mean age: 67¡¾8,
male: 5, female: 27). Seventy nine vertebral fractures were detected (38 thoracic/thoracolumbar lesions and 41
lumbar lesions), which were classified by type of deformity (wedge, biconcave or compression). The patterns and
locations of increased uptakes were examined and analyzed. Results: Forty seven wedge fractures, 20 biconcave
fractures and 12 compression fractures were found. Diffuse and asymmetric uptakes were common in fractured
bodies. More than one uptake were examined in 69 posterior elements of fractured vertebrae (87.3%) including 40
of 47 wedge fractures (85.1%), 17 of 20 biconcave fractures (85.0%) and 12 of 12 compression fractures (100%).
Wedge fractures were predominant fracture in thoracic/thoracolumbar spine whereas incidence of biconcave or
compression type was similar to that of wedge fracture in lumbar spine (p=0.04). Spinous process uptake was
more frequently seen in lumbar lesions than thoracic/thoracolumbar lesions (p=0.009). Facet joint uptake in
biconcave fracture was more common in lumbar spine (92.3%) than thoracic/thoracolumbar spine (57.1%). Spinous
process uptake in biconcave fracture was also more frequently detected in lumbar spine (p=0.043). Conclusion:
Bone SPECT was useful in the evaluation of osteoporotic vertebral fracture, especially posterior elements of
vertebrae.(Korean J Nucl Med 38(6):522-527, 2004) |
