为了确定与骨扫描相关的X线片的可靠性，在没有已知转移的癌症患者中显示一个或两个新的异常，对306个显示此类病变的扫描进行了回顾性研究。总体而言，14%的病变被证明是恶性的。43%的新骨扫描病变的初始影像学解释正常;这些病变中有17%是转移瘤。38%的异常在X线片上被确定为良性过程;只有一个（1%）是转移。12%的新骨扫描病变与影像学异常相关，这些异常被认为提示或符合转移，其中24%和71%分别被证明是转移。在有一个或两个新的骨扫描异常的癌症患者中，显示良性异常的相关X线片是可靠的。然而，如果X线片正常或显示被认为提示或符合转移的结果，则需要进一步评估或随访。
To determine the reliability of radiographs obtained for correlation with bone scans showing one or two new abnormalities in cancer patients without known metastases, a retrospective study of 306 scans showing such lesions was performed. Overall, 14% of the lesions proved to be malignant. The initial radiographic interpretation was normal for 43% of the new bone scan lesions; 17% of these lesions were metastases. A benign process was identified on radiographs for 38% of the abnormalities; only one (1%) was a metastasis. Twelve percent of new bone scan lesions correlated with radiographic abnormalities considered either suggestive of or consistent with metastasis, of which 24% and 71%, respectively, proved to be metastases. In cancer patients with one or two new bone scan abnormalities, correlative radiographs showing a benign abnormality are reliable. However, if the radiographs are either normal or show findings considered suggestive of or consistent with metastasis, further evaluation or follow-up is warranted.
