The findings and the diagnostic value of modern imaging techniques (CT and MRI) to evaluate laryngeal carcinoma are reviewed. At all three anatomic levels of the larynx, CT is able to assess additional findings compared to endoscopy which allow superior staging of the neoplasms. Concerning all T-stages (1-4) a correct classification is possible in 70-80% of the cases with CT. The N-stages are classified correctly in around 85%. The limitations of CT include the subtle evaluation of tumor-induced cartilage and bone defects and the detection of superficial tumors. The experience with MRI of laryngeal cancer is still limited. The advantage of MRI, compared to CT, are an improved contrast between tumor and muscle using Gd-DTPA as a contrast agent and the ability of multiplanar imaging. However, MRI in the laryngeal region is still associated with a low spatial resolution, long examination time and moving artifacts. In the next future CT will remain the imaging procedure of first choice to evaluate laryngeal cancer.
本文综述了现代成像技术（CT和MRI）在评估喉癌方面的研究结果及诊断价值。在喉的所有三个解剖层面上，与内镜检查相比，CT能够评估更多的发现，从而实现对肿瘤更准确的分期。对于所有T分期（1 - 4期），CT在70 - 80%的病例中能够进行正确分类。N分期的正确分类率约为85%。CT的局限性包括对肿瘤引起的软骨和骨缺损的细微评估以及浅表肿瘤的检测。喉癌MRI的经验仍然有限。与CT相比，MRI的优势在于使用钆喷酸葡胺（Gd - DTPA）作为造影剂时肿瘤与肌肉之间的对比度提高，以及具有多平面成像能力。然而，喉部区域的MRI仍存在空间分辨率低、检查时间长和运动伪影等问题。在可预见的未来，CT仍将是评估喉癌的首选成像检查方法。
