Computed tomography was evaluated for its accuracy in diagnosing mediastinal node metastases, direct chest wall invasion, and direct mediastinal invasion by lung cancer among 61 patients who subsequently underwent surgery. Using 15-mm diameter or larger mediastinal lymph nodes as the criterion for metastasis, the sensitivity was 36% (8/22); the specificity was 92% (34/37). The accuracy for direct chest wall invasion was relatively high, with a sensitivity of 100% (7/7) and a specificity of 92% (22/24). Direct mediastinal invasion had a sensitivity of 67% (4/6) and a specificity of 91% (10/11). These results suggest that the ability of computed tomography to diagnose mediastinal lymph node metastasis when such nodal size is used as a criterion is limited.
对61例随后接受手术的患者，评估了计算机断层扫描在诊断纵隔淋巴结转移、直接胸壁侵犯和肺癌直接纵隔侵犯方面的准确性。以直径15毫米或更大的纵隔淋巴结作为转移标准，敏感性为36%（8/22）；特异性为92%（34/37）。直接胸壁侵犯的准确性相对较高，敏感性为100%（7/7），特异性为92%（22/24）。直接纵隔侵犯的敏感性为67%（4/6），特异性为91%（10/11）。这些结果表明，当以此种淋巴结大小作为标准时，计算机断层扫描诊断纵隔淋巴结转移的能力有限。
