A significant number of girls develop an adolescent idiopathic scoliosis and require repeated full-length radiographs of the spine. Since Nash's publication in 1979 [16], there has been considerable concern expressed about protecting them from excessive radiation, and particularly from the development of radiation-induced breast tumours. We present a study which compares the differences in radiation dose using different techniques, specifically, the use of a posteroanterior projection, very fast rare earth screens and progressive wedge-shaped filtration. The use of a posteroanterior projection reduced the sternal exposure by 98.9% and the breast skin exposure by 92%. A combination of all three techniques reduced the sternal exposure by 99.5%. We recommend that these should be used routinely to reduce the radiation hazard to children with an adolescent idiopathic scoliosis.
相当数量的女孩会患上青少年特发性脊柱侧弯，需要反复拍摄脊柱全长X光片。自1979年纳什发表相关研究[16]以来，人们一直非常关注如何保护她们免受过量辐射，尤其是预防辐射诱发的乳腺肿瘤。我们开展了一项研究，比较了使用不同技术时的辐射剂量差异，具体而言，比较了后前位投照、超快速稀土增感屏和渐进楔形滤线器的使用情况。采用后前位投照可使胸骨受照剂量降低98.9%，乳房皮肤受照剂量降低92%。三种技术联合使用可使胸骨受照剂量降低99.5%。我们建议常规使用这些技术，以降低青少年特发性脊柱侧弯患儿的辐射危害。
