The authors describe the computed tomography (CT) and magnetic resonance imaging (MRI) findings in a patient with thrombosis of the inferior vena cava (IVC) and azygous continuation of the IVC caused by bronchogenic carcinoma. CT has been touted as the modality of choice for mediastinal evaluation. MRI is presently considered to be the initial modality of choice for mediastinal vessel evaluation. MRI is noninvasive, there is no radiation dose to the patient, multiplanar imaging can be done, and there is no need for iodinated contrast material. The satisfactory evaluation of an individual patient may require the use of MRI and CT in a complementary fashion.
作者描述了一名因支气管源性癌导致下腔静脉（IVC）血栓形成及IVC奇静脉延续的患者的计算机断层扫描（CT）和磁共振成像（MRI）表现。CT一直被吹捧为纵隔评估的首选方式。目前，MRI被认为是纵隔血管评估的首选初始方式。MRI是非侵入性的，患者无需接受辐射剂量，可进行多平面成像，且无需使用碘化造影剂。对个体患者的满意评估可能需要以互补的方式使用MRI和CT。
