Readers of chest radiographs often comment on the presence of osteoporosis. We have hypothesized that diagnoses of osteoporosis from chest films are not reliable even when made by experienced radiologists. To test this hypothesis, we had nine radiologists estimate the degree of bone density seen on 45 lateral chest films. We compared their estimates of bone density to the results of dual photon bone densitometry of the lumbar spine. We found that there was little ability to accurately diagnose osteoporosis by chest film since the group of nine readers achieved accuracies ranging from 0.59 to 0.64. Therefore, we feel it is unjustified to comment upon the presence or absence of osteoporosis on the basis of chest films.
胸部X光片的阅片者常常会对骨质疏松的情况发表评论。我们推测，即使由经验丰富的放射科医生进行判断，通过胸部X光片诊断骨质疏松也不可靠。为了验证这一推测，我们让九位放射科医生评估45张胸部侧位片上的骨密度程度。我们将他们对骨密度的评估结果与腰椎双能光子骨密度测定的结果进行了比较。我们发现，通过胸部X光片准确诊断骨质疏松的能力很有限，因为这九位阅片者的诊断准确率在0.59至0.64之间。因此，我们认为基于胸部X光片对骨质疏松的有无进行评论是不合理的。
