We describe the use of computed tomography (CT) in diagnosing and documenting diaphragmatic paralysis in a patient with right lung cancer that invaded the mediastinum. The patient was unable to breath hold during CT scanning, and the images were degraded by motion artifact. Motion artifact, however, was noted only in the left lung. In patients with suspected phrenic nerve dysfunction who are having chest CT for any reason, we suggest obtaining several dynamic images at the lung bases during forced exhalation. The lack of motion artifact in the lung parenchyma may be useful for diagnosing phrenic nerve injury and hemidiaphragm paralysis.
我们描述了计算机断层扫描（CT）在诊断和记录一名右肺癌侵犯纵隔患者的膈肌麻痹中的应用。该患者在CT扫描期间无法屏气，图像因运动伪影而质量下降。然而，运动伪影仅在左肺被观察到。对于因任何原因进行胸部CT检查且怀疑有膈神经功能障碍的患者，我们建议在用力呼气时在肺底部获取几张动态图像。肺实质中无运动伪影可能有助于诊断膈神经损伤和半膈肌麻痹。
