选择性颈淋巴结照射是治疗临床N0 期头颈部肿瘤的常用方式 ,三维适形放射治疗和调强放射治疗的临床应用要求基于影像学的淋巴结分区与勾划的准则。本文对几种常用的颈淋巴结的影像学分区方法以及在适形放射治疗中的应用情况作一详细综述。
Selective cervical lymph node irradiation is a common treatment for head and neck cancer in clinical stage N0. The clinical application of three-dimensional conformal radiotherapy and intensity-modulated radiation therapy requires guidelines for imaging lymph node zoning and delineation. In this paper, several commonly used cervical lymph node imaging zoning methods and applications in conformal radiotherapy for a detailed review.
