The visibility limit of soft tissue nodules in the lungs is 3 mm on a chest radiography, yet lung cancers are rarely detected until the tumors are 8-10 mm in size. This paper presents data on the size distribution of nodular lung cancers and noncancerous nodular noise on chest radiographs. These data are analyzed in decision-making terms and show that when the size is 8-10 mm, observers can separate true cancers from noise that mimics cancer, with a probability of being correct, or a predictive value, of 90% or more.
在胸部X光片上，肺部软组织结节的可见极限为3毫米，但肺癌在肿瘤大小达到8 - 10毫米之前很少被检测到。本文展示了胸部X光片上结节性肺癌和非癌性结节状噪声的大小分布数据。这些数据从决策角度进行了分析，结果表明，当结节大小为8 - 10毫米时，观察者能够以90%或更高的正确概率（即预测值）将真正的癌症与模拟癌症的噪声区分开来。
