The stimulus for this investigation concerning radiation exposure during radiography of the spine, particularly in children with scoliosis, is the fact that there are no data in the literature. In 16 series of measurements we studied the effect of grids, kilovoltage, focus-film distance and film-screen systems using dosimeters. The use of grids led to a 5-7 times increase in radiation dose compared with exposures without grids. For this reason grids are not recommended for serial examinations in cases of scoliosis. It is easier to evaluate the spine on a single large film than on several small films and radiation dose is also halved. Therefore, the use of large single films is recommended, particularly for children and adolescents.
本次关于脊柱X光摄影（尤其是脊柱侧弯儿童）时辐射暴露情况的调查，是因为文献中尚无相关数据。我们通过剂量仪对16组测量数据进行研究，分析了滤线栅、千伏电压、焦-片距和增感屏-胶片系统的影响。使用滤线栅会使辐射剂量相较于不使用滤线栅时增加5至7倍。因此，不建议在脊柱侧弯病例的系列检查中使用滤线栅。在一张大胶片上评估脊柱比在几张小胶片上更容易，而且辐射剂量也会减半。所以，建议使用大尺寸单张胶片，尤其是对于儿童和青少年。
