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, was investigated in 73 female subjects who also had photon absorptiometry done on calcaneus and antebrachium. Comparison of the 2 methods reveals that there is no close relationship between the results. Photon absorptiometry for evaluating bone mineral content proved its precision and accuracy, while conventional X-ray film evaluation of bone mineral seems to lack a proper foundation.
