Different ways to minimize the gonadal dose in lumbar spine radiography have been studied. Two hundred and fifty lumbar spine radiographs were reviewed to assess the clinical need for lateral L5/S1 projection. Modern film/screen combinations and gonadal shielding of externally scattered radiation play a major role in the reduction of the genetic dose. The number of exposures should be minimized. Our results show that two projections, anteroposterior (AP) and lateral, appear to be sufficient in routine radiography of the lumbar spine.
人们已经研究了在腰椎X线摄影中使性腺剂量最小化的不同方法。回顾了250张腰椎X线片，以评估L5/S1侧位投照的临床必要性。现代胶片/增感屏组合以及对外部散射辐射的性腺屏蔽在减少遗传剂量方面起着主要作用。应尽量减少曝光次数。我们的结果表明，前后位（AP）和侧位这两种投照方式在腰椎常规X线摄影中似乎就足够了。
