MRI has been used increasingly in the evaluation of nasopharyngeal carcinoma (NPC) because of its good tissue contrast and multiplanar capacity. Although there are some controversies in assessing skull base invasion and cervical metastatic adenopathy, recent reports demonstrate that MRI is currently better than or as good as CT in defining the extent of NPC. During follow-up of patients with NPC after radiotherapy, MRI is also more effective than CT in demonstrating tumor recurrence and in detecting postradiation complications. However, the difficulty of using MRI to detect early mucosal recurrence and to differentiate postradiation tissue changes from local tumor recurrence should be recognized. This paper reviews the literature regarding MRI of NPC related to radiotherapy, with special emphasis on treatment planning, recurrence assessment, and complication detection.
由于具有良好的组织对比度和多平面成像能力，磁共振成像（MRI）在鼻咽癌（NPC）评估中的应用越来越广泛。尽管在评估颅底侵犯和颈部转移性淋巴结病方面存在一些争议，但最近的报告表明，在确定NPC的范围方面，MRI目前优于CT或与CT相当。在NPC患者放疗后的随访期间，MRI在显示肿瘤复发和检测放疗后并发症方面也比CT更有效。然而，应认识到使用MRI检测早期黏膜复发以及区分放疗后组织变化与局部肿瘤复发的困难。本文回顾了有关NPC放疗相关MRI的文献，特别强调治疗计划、复发评估和并发症检测。
