Thirty-eight patients with mediastinal and/or hilar masses were imaged by computed tomography (CT) and magnetic resonance imaging (MRI). Results were analyzed retrospectively regarding the ability to demonstrate the masses, their number, size, definition, location and tissue characteristics. CT and MRI showed equivalent results in 32 cases; additional information was obtained in two patients by CT, in four patients by MRI. In view of the specific advantages and limitations of both CT and MRI we believed that in patients with mediastinal and/or hilar masses, contrast enhanced CT remains the procedure of choice after performing plain chest radiographs; in certain cases MRI will prove useful for further evaluation.
38例纵隔和/或肺门肿块患者接受了计算机断层扫描（CT）和磁共振成像（MRI）检查。回顾性分析了CT和MRI在显示肿块、肿块数量、大小、清晰度、位置及组织特征方面的结果。32例患者CT和MRI结果相当；2例患者通过CT获得了额外信息，4例患者通过MRI获得了额外信息。鉴于CT和MRI各自的特定优势与局限性，我们认为对于纵隔和/或肺门肿块患者，在进行胸部平片检查后，增强CT仍是首选检查方法；在某些情况下，MRI对进一步评估将很有用。
