连续 1085 次胸部 X 光检查中记录了所有检测到的异常结果。每项发现均按描述性标准进行分类，并根据微妙程度进行分级。使用随访或多个读者在 100 个案例的随机样本中评估解释的准确性。 70% 的标准检查和 93% 的床边检查显示异常结果。肺部浸润是最常检测到的异常，占异常病例的 55%。大约 5% 的异常病例中存在非钙化肺结节和气胸。最常见的细微发现是静脉导管、肺部浸润、气胸、肋骨病变和肺部结节（按频率降序排列）。结论是，在评估数字射线照相等新成像方式时，在观察者测试中使用这些发现的选定示例是合理的。
All detected abnormal findings were recorded for 1085 consecutive chest x-ray examinations. Each finding was classified by descriptive criteria and graded for subtlety. Accuracy of interpretation was evaluated in a randomized sample of 100 cases using follow-up or multiple readers. Seventy percent of standard examinations and 93% of bedside examinations revealed abnormal findings. Pulmonary infiltrates were the most commonly detected abnormality, being present in 55% of abnormal cases. Noncalcified pulmonary nodules and pneumothoraces were each present in approximately 5% of abnormal cases. The most commonly encountered subtle findings were due to intravenous catheters, pulmonary infiltrates, pneumothoraces, rib lesions, and pulmonary nodules in descending order of frequency. It is concluded that it is reasonable to use selected examples of these findings in observer tests when evaluating new imaging modalities such as digital radiography.
