Planar bone scintigraphy (PBS) and single-photon emission computed tomography (SPECT) were compared in 19 adults with radiographic evidence of spondylolysis and/or spondylolisthesis. SPECT was more sensitive than PBS when used to identify symptomatic patients and sites of "painful" defects in the pars interarticularis. In addition, SPECT allowed more accurate localization than PBS. In 6 patients, spondylolysis or spondylolisthesis was unrelated to low back pain, and SPECT images of the posterior neural arch were normal. The authors conclude that when spondylolysis or spondylolisthesis is the cause of low back pain, pars defects are frequently heralded by increased scintigraphic activity which is best detected and localized by SPECT.
对19名有椎弓根峡部裂和/或脊椎滑脱影像学证据的成年人进行了平面骨闪烁扫描（PBS）和单光子发射计算机断层扫描（SPECT）比较。当用于识别有症状的患者以及关节突部“疼痛性”缺损部位时，SPECT比PBS更敏感。此外，SPECT比PBS定位更准确。6例患者的椎弓根峡部裂或脊椎滑脱与腰痛无关，神经弓后部的SPECT图像正常。作者得出结论，当椎弓根峡部裂或脊椎滑脱是腰痛的原因时，闪烁扫描活性增加常常预示着关节突部缺损，而SPECT能最好地检测和定位这种情况。
