The posteroanterior projection was studied to determine if it could be a substitute for the commonly used anteroposterior projection as a method of reducing x-ray exposure to specific radiosensitive organs during intracranial tomography and scoliosis radiography. The use of the posteroanterior projection resulted in a reduction of 95% in exposure to the lens of the eye during intracranial tomography and of more than 90% to the thyroid, sternum, and breasts during scoliosis radiography. In addition to the major reduction in radiation exposure, the diagnostic capability of the examination was not reduced and comfort in most patients was not affected.
