病理学表现：实变涉及病变的渗出或其他产物取代了肺泡内的空气使肺实化（如在感染性肺炎中）。ZzE影像园XCTMR.com
X 线胸片和CT 表现： 实变表现为肺实质衰减均匀增加， 掩盖了其内的血管和气道壁的边缘，可ZzE影像园XCTMR.com
有空气支气管征。实变肺的衰减特征对鉴别诊断帮助不大（如，类脂性肺炎中的衰减减低，在乙胺碘呋酮中毒时的衰减增加）。ZzE影像园XCTMR.com

Pathology.—Consolidation refers to an exudate or other product of disease that replaces alveolar air, rendering the lung solid (as in infective pneumonia). ZzE影像园XCTMR.com

Radiographs and CT scans.—Consolidation appears as a homogeneous increase in pulmonary parenchymal attenuation that obscures the margins of vessels and airway walls (Fig 1). An air bronchogram may be present. The attenuation characteristics of consolidated lung are only rarely helpful in differential diagnosis (eg, decreased attenuation in lipoid pneumonia and increased in amiodarone toxicity ).
