Sentinel node mapping is becoming a routine procedure for staging of various malignancies, because it can determine lymph node status more precisely. Due to anatomical problems, localizing sentinel nodes in the head and neck region on the basis of conventional images can be difficult. New diagnostic tools can provide better visualization of sentinel nodes. In an attempt to keep up with possible scientific progress, this article reviews new and innovative tools for sentinel node localization in this specific area. The overview comprises a short introduction of the sentinel node procedure as well as indications in the head and neck region. Then the results of SPECT/CT for sentinel node detection are described. Finally, a portable gamma camera to enable intraoperative real-time imaging with improved sentinel node detection is described.
前哨淋巴结绘图已成为各种恶性肿瘤分期的常规程序，因为它可以更精确地确定淋巴结状态。由于解剖问题，基于常规图像在头颈部定位前哨淋巴结可能具有挑战性。新的诊断工具可以更好地显示前哨淋巴结。为了跟上可能的科学进步，本文综述了该特定区域中用于前哨淋巴结定位的新型创新工具。概述包括对前哨淋巴结程序以及头颈部适应证的简短介绍。然后描述了 SPECT/CT 用于前哨淋巴结检测的结果。最后，描述了一种便携式伽马相机，可实现术中实时成像，从而提高前哨淋巴结检测的准确性。
