Seventeen patients with histologically proved bronchogenic carcinoma involving the superior pulmonary sulcus (Pancoast tumors) were evaluated by computed tomography (CT), including sagittal and coronal image reconstruction. Compared to conventional radiography, axial transverse CT images provided, in all cases, additional information regarding local tumor extension and metastatic spread. Mediastinal involvement either by lymphangitic spread or direct tumor extension was present in 11 cases. In 4 patients plain films clearly showed mediastinal disease; however, CT more clearly delineated overall tumor extent, thus facilitating improved therapy planning. In a further 4 cases CT showed mediastinal involvement after plain films had been read as normal, and in an additional 3 instances metastatic involvement was either greatly underestimated (2 patients) or overestimated (1 patient) on the plain films. Reconstructed images in sagittal and coronal planes lacked detail but facilitated a three-dimensional concept of tumor extent and relationship of tumor to adjacent structures, particularly major blood vessels.
17例经组织学证实的累及肺上沟的支气管源性癌（潘科斯特瘤）患者接受了计算机断层扫描（CT）检查，包括矢状面和冠状面图像重建。与传统放射摄影相比，轴向横断CT图像在所有病例中均提供了有关局部肿瘤扩展和转移扩散的额外信息。11例患者存在通过淋巴管扩散或肿瘤直接蔓延引起的纵隔受累。4例患者的平片清晰显示纵隔病变；然而，CT更清楚地描绘了肿瘤的整体范围，从而有助于改进治疗方案的制定。另外4例患者在平片读片为正常后CT显示纵隔受累，还有3例患者平片对转移受累的评估要么严重低估（2例患者）要么高估（1例患者）。矢状面和冠状面的重建图像缺乏细节，但有助于形成肿瘤范围以及肿瘤与相邻结构，特别是主要血管关系的三维概念。
