The computed tomographic appearance of acute and chronic radiation change in the thorax is described. Acute radiation pneumonitis demonstrates patchy, confluent regions of increased pulmonary attenuation. Chronic changes include soft tissue density fibrotic changes that blend smoothly with the pleural surfaces and adjacent mediastinal structures. Also seen are bronchiectatic changes and distortion of normal intrathoracic anatomic relationships. Both the acute and chronic changes usually make linear lateral margins with adjacent aerated lung. Development of a discrete mass or focal cavitation after the radiation changes have become stable is suspect for recurrent tumor or infection.
描述了胸部急性和慢性辐射变化的计算机断层扫描表现。急性放射性肺炎表现为肺部密度增加的斑片状、融合性区域。慢性变化包括与胸膜表面和相邻纵隔结构平滑融合的软组织密度纤维化改变。还可见支气管扩张性改变和正常胸内解剖关系的扭曲。急性和慢性改变通常与相邻的充气肺形成线性边缘。在辐射变化稳定后出现离散性肿块或局灶性空洞，应怀疑为肿瘤复发或感染。
