Imaging methods play a significant role in the diagnosis of oropharynx and oral cavity lesions. Contrast-enhanced CT has been established as the baseline technique for T- and N-staging of malignomas. CT yields significant additional information to clinical methods, especially in examining large tumors. With an examination time of only 10 minutes, it is the method of choice. MR imaging requires more time (40 minutes or more) but the superior tissue contrast allows the depiction of smaller lesions. The use of fast gradient-echo sequences in combination with the application of gadolinium diethylenetriamine penta-acetic acid offers new perspectives. High-resolution real-time ultrasound in the hands of an experienced examiner may be helpful because it is easily available; however, it does not allow a complete tumor staging.
成像方法在口咽和口腔病变的诊断中起着重要作用。增强CT已被确立为恶性肿瘤T分期和N分期的基线技术。CT能为临床方法提供重要的额外信息，尤其是在检查大型肿瘤时。由于检查时间仅需10分钟，它是首选方法。磁共振成像需要更多时间（40分钟或更长），但其卓越的组织对比度能够显示较小的病变。使用快速梯度回波序列并结合钆喷酸葡胺的应用提供了新的视角。经验丰富的检查者操作的高分辨率实时超声可能会有所帮助，因为它易于获得；然而，它无法进行完整的肿瘤分期。
