作者开发了一种计算机系统，可以在胸部计算机断层扫描中自动识别结节，量化其直径，并在随访时评估大小变化。自动结节检测系统在16项研究（8项初始研究和8项随访研究）中识别了8例已知结节的肿瘤患者的370个结节中的318个（86%）。计算机对结节大小变化的评估与胸部放射科医生的评估相匹配（斯皮尔曼等级相关系数，0.932）。
The authors developed a computer system that automatically identifies nodules at chest computed tomography, quantifies their diameter, and assesses for change in size at follow up. The automated nodule detection system identified 318 (86%) of 370 nodules in 16 studies (eight initial and eight follow-up studies) obtained in eight oncology patients with known nodules. Assessment of change in nodule size by the computer matched that by the thoracic radiologist (Spearman rank correlation coefficient, 0.932).
