Bone scintigraphy and radiography were performed in seven children with back pain. Six of the children with radiographic evidence of a pars interarticularis defect also had abnormal scintigrams. Increased uptake of the bone imaging agent occurred at six of the ten sites of radiographic pars interarticularis defects, implying increased bone metabolic activity. However, the location of scintigraphic abnormalities did not correspond to the location of radiographic abnormalities in several cases. Possible explanations for the discordant findings are: (a) normal bone metabolism at the site of an old spondylolysis and (b) radiographically inapparent stress fractures. Measurements of absorbed radiation dose indicate that plain radiography, including oblique views where appropriate, has a lower absorbed radiation dose than scintigraphy or tomography and should be performed prior to these studies.
对7名背痛儿童进行了骨闪烁显像和X线摄影检查。6名有椎弓根峡部裂影像学证据的儿童骨闪烁显像也异常。在10处椎弓根峡部裂的X线摄影部位中，有6处骨显像剂摄取增加，提示骨代谢活性增强。然而，在几例病例中，骨闪烁显像异常的部位与X线摄影异常的部位并不对应。对这些不一致结果的可能解释为：(a)陈旧性椎弓根峡部裂部位的骨代谢正常；(b)X线摄影未显示的应力性骨折。吸收辐射剂量的测量表明，普通X线摄影，包括必要时的斜位片，其吸收辐射剂量低于闪烁显像或体层摄影，应在这些检查之前进行。
