Gonadal dose reduction in lumbar spine radiography.
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.
