CT and MRI manifestations of 52 peripheral lung cancers located close to the pleural surface or mediastinal structures were studied correlating with the surgical and pathologic findings. Rib destruction as shown by CT and T2 weighted MRI showing the encroachment of tumor upon the chest wall were crucial in demonstrating chest wall invasion. An obtuse chest wall intersecting angle and the length of the neighboring borders of the tumor and chest wall were of limited value. Local pleural thickening was observed near the tumor in 54% of cases, over half of them showed obtuse angle between the tumor and the chest wall but without tumor invasion. T2 weighted MRI was more reliable than CT by showing different signal intensities for pleural thickening, inflammation, localized pleural effusion or tumor invasion to chest wall soft tissue.
对52例位于胸膜表面或纵隔结构附近的周围型肺癌的CT和MRI表现进行了研究，并与手术及病理结果相关联。CT显示的肋骨破坏以及T2加权MRI显示肿瘤对胸壁的侵犯对于证实胸壁侵犯至关重要。胸壁相交钝角以及肿瘤与胸壁相邻边界的长度价值有限。54%的病例在肿瘤附近观察到局部胸膜增厚，其中超过一半显示肿瘤与胸壁之间为钝角，但无肿瘤侵犯。T2加权MRI通过显示胸膜增厚、炎症、局限性胸腔积液或肿瘤对胸壁软组织侵犯的不同信号强度，比CT更可靠。
