Incidental findings, including pulmonary nodules, on computed tomography coronary angiography (CTCA) are common. Previous authors have suggested CTCA could allow opportunistic screening for lung cancer, though the lung cancer risk profile of this patient group has not previously been established. Smoking histories of 229 patients undergoing CTCA at two tertiary hospitals were reviewed and only 25% were current or former smokers aged 55-80 years old. Less than half of this group were eligible for screening based on the PLCO risk model. We conclude that routine screening in the form of full thoracic field imaging, of individuals undergoing CTCA is not appropriate as it would likely result in net harm.
计算机断层扫描冠状动脉造影（CTCA）中的偶然发现，包括肺结节，很常见。先前的作者认为CTCA可用于肺癌的机会性筛查，尽管此前尚未确定该患者群体的肺癌风险特征。回顾了两家三级医院229例接受CTCA检查患者的吸烟史，只有25%是年龄在55 - 80岁的当前或既往吸烟者。根据PLCO风险模型，该组中不到一半的人符合筛查条件。我们得出结论，对接受CTCA检查的个体进行全胸野成像形式的常规筛查是不合适的，因为这可能会导致净危害。
