The usefulness of brain scans for detecting unsuspected cerebral metastasis in patients with carcinoma of the lung was studied in a group of 35 such patients who had had routine brain scans as part of the initial evaluation. Seven (20%) had scans that were positive for tumor, but six of these seven had neurologic deficits corresponding to the brain-scan abnormality. Routine brain scans for evaluation of carcinoma of the lung are not justified if neurologic examination is normal.
对一组35例肺癌患者进行了研究，以探讨脑部扫描在检测未被怀疑的脑转移方面的作用，这些患者在初始评估时已进行了常规脑部扫描。7例（20%）扫描显示肿瘤阳性，但这7例中有6例存在与脑部扫描异常相对应的神经功能缺损。如果神经学检查正常，对肺癌患者进行常规脑部扫描以进行评估是不合理的。
