title: A comparison of two methods for estimating bone loss.
abstract: The presence or absence of osteopenia, as judged by routine X-ray examination of the lumbar spine supplemented by X-ray evaluation of calcaneus, has been investigated in 73 female subjects who also had photon absorptiometry done on calcaneus and antebrachiúm. Comparison of the two methods reveals that there is no close relationship between the results. Photon absorptiometry for evaluating bone mineral content has proven its precision and accuracy, while conventional X-ray film evaluation of bone mineral seems to lack a proper foundation.
