The hybrid technique of PET/CT has significantly impacted the imaging and management of HNSCC since its introduction in 2001 and has become the technique of choice for imaging of this cancer. Diagnostic FDG-PET/CT is useful for identification of an unknown primary tumor, delineation of extent of primary tumor, detection of regional lymph node involvement even in a normal-sized node, detection of distant metastases and occasional synchronous primary tumor, assessment of therapy response, and long-term surveillance for recurrence and metastases. The role of PET/CT is evolving in radiation therapy planning. Combined diagnostic PET/CT provides the best anatomic and metabolic in vivo information for the comprehensive management of HNSCC.
自 2001 年引入以来,PET/CT 混合技术对 HNSCC 的影像学诊断和治疗产生了重大影响,已成为此类癌症影像学检查的首选方法。诊断用 FDG-PET/CT 可用于发现未知原发灶、明确原发灶范围、即使在正常大小的淋巴结中也能发现局部淋巴结转移、发现远处转移和偶尔的同时性原发灶、评估治疗反应以及长期随访复发和转移情况。在放射治疗计划中,PET/CT 的作用也在不断发展。联合诊断用 PET/CT 为 HNSCC 的综合管理提供了最佳的解剖和代谢的体内信息。
