摘要
CT作为基本的鼻咽癌影像学评估手段,在鼻咽癌分期中发挥着重要作用。MRI具有较高的软组织分辨率,在原发肿瘤的侵犯范围、颅底骨质破坏及咽后淋巴结的界定方面明显优越于CT。PET/CT融合了功能影像和解剖成像,对原发灶的累及范围、远处转移的筛查及肿瘤复发的诊断具有独特的优势。本文综述了这3种影像学检查手段的优缺点及对鼻咽癌第七版UICC分期、复发后再分期的价值。
As the basic imaging modality,CT plays an important role in TNM staging of nasopharyngeal carcinoma.Due to higher soft tissue resolution,MRI is more sensitive than CT in demonstrating tumor extent and the involvement of surrounding structures such as the skull base erosion,and the enlargement of retropharyngeal lymph nodes.PET-CT combines functional imaging and cross-sectional imaging offering a unique advantage in defining the primary tumor extent,distant metastases and the evaluation of tumor recurrence.In this paper,we reviewed the strengths and weaknesses of the 3 imaging methods,and their roles in the 7th edition of UICC staging system for primary and recurrent nasopharyngeal carcinoma.
