[Evaluation of usefulness of bone SPECT for lumbar spondylolysis].

Abstract

The purpose of this study was to evaluate the usefulness of 99mTc-MDP SPECT (bone SPECT) for lumbar spondylolysis. We analyzed 11 cases with 17 lesions. All cases were compared using plain radiography, computed tomography (CT), planar bone scintigraphy (PBS), and bone SPECT. Four lesions that showed a wide defect on CT were negative on bone SPECT and may have been chronic lesions. Thirteen lesions that were positive on bone SPECT were narrow or showed no defect on CT and may have been early lesions. Two cases showed no defect on CT but were positive on bone SPECT, and one of them progressed to bilateral spondylolysis after one year. This may have been a very early lesion. Thus bone SPECT is useful for the diagnosis of lumbar spondylolysis, especially in its early stage.
