Preoperative oblique hilar tomography was used to evaluate hilar lymph nodes in 150 patients with clinically resectable bronchogenic carcinoma. CT was also used in the evaluation of mediastinal lymph nodes in 50 of these patients. Subsequently, all patients underwent mediastinoscopy and/or thoracotomy. Hilar and mediastinal nodes were evaluated for the presence of metastasis, and these findings were then correlated with the radiographic findings of oblique hilar tomography and CT. CT was found to be a reliable method for prethoracotomy staging of bronchogenic carcinoma and for selecting patients for mediastinoscopy. The sensitivity of CT for evaluation of mediastinal nodal metastasis was 83% and the specificity was 90%. Thus patients with negative mediastinal CT need not undergo mediastinoscopy prior to thoracotomy, while mediastinoscopy and biopsy should be done in patients with enlarged mediastinal nodes on CT. Oblique hilar tomography is an accurate method for evaluation of hilar adenopathy and for predicting mediastinal involvement by extrapolation.
术前斜位肺门体层摄影术用于评估150例临床可切除的支气管肺癌患者的肺门淋巴结。其中50例患者还采用CT评估纵隔淋巴结。随后，所有患者均接受了纵隔镜检查和/或开胸手术。评估肺门和纵隔淋巴结有无转移，然后将这些结果与斜位肺门体层摄影术和CT的影像学结果进行对比。发现CT是支气管肺癌开胸术前分期以及选择纵隔镜检查患者的可靠方法。CT评估纵隔淋巴结转移的敏感性为83%，特异性为90%。因此，纵隔CT阴性的患者在开胸术前无需接受纵隔镜检查，而CT显示纵隔淋巴结肿大的患者应进行纵隔镜检查和活检。斜位肺门体层摄影术是评估肺门淋巴结病以及通过推断预测纵隔受累情况的准确方法。
