The mediastinal lines correspond to the contours of the middle and upper mediastinum, and represent the edges of a dense, pleural covered structure marginated by the air within the lung. The mediastinal lines derive their names from the adjacent organs: 1) The posterior mediastinal junction line (where both lungs meet posteriorly, just before the vertebral column). 2) The anterior mediastinal junction line (where both lungs meet anteriorly, behind the sternum). 3) The right paratracheal stripe (where the right lung meets the trachea). 4) The esophageal-pleural stripe (which disappears at the level of the arch of the Azygos vein that divides the right lung from the esophagus. 5) The Azygos-pleural line (where the arch of the Azygos vein meets the right lung). 6) The esophageal-pleural line (where the right esophageal wall meets the right lung). 7) The para-aortic line (that is the most constant). 8) and 9) The left and right paraspinous lines (whereof the right is the most often visible). The absence of one of the mediastinal lines is sometimes insignificant, since it can be caused by anatomical variations or by the conditions of the picture. C.T. explains the formation's mechanism of these mediastinal lines, explains the anatomic reasons for their possible absence or displacement and often provides us with their etiology. C.T. offers a simple, reliable and atraumatic method in cases of displaced or vanished mediastinal lines, and should replace standard tomography of the mediastinum.
纵隔线与中纵隔和上纵隔的轮廓相对应，代表了一个被肺内气体所界定的、被胸膜覆盖的致密结构的边缘。纵隔线因其相邻器官而得名：1）后纵隔交界线（两肺在脊柱前方后方相遇处）。2）前纵隔交界线（两肺在胸骨后方前方相遇处）。3）右气管旁条纹（右肺与气管相遇处）。4）食管 - 胸膜条纹（在奇静脉弓水平消失，奇静脉弓将右肺与食管分开）。5）奇静脉 - 胸膜线（奇静脉弓与右肺相遇处）。6）食管 - 胸膜线（右食管壁与右肺相遇处）。7）主动脉旁线（最恒定）。8）和9）左、右脊柱旁线（其中右脊柱旁线最常可见）。纵隔线之一的缺失有时并无大碍，因为它可能是由解剖变异或图像条件所致。CT解释了这些纵隔线的形成机制，解释了它们可能缺失或移位的解剖学原因，并常常为我们提供其病因。对于移位或消失的纵隔线，CT提供了一种简单、可靠且无创的方法，应取代纵隔的标准体层摄影。
