摘要 目的分析口腔癌正电子发射断层(PET)和计算机断层(CT)成像的特点,探讨PET/CT在口腔癌诊断中的应用价值。方法回顾分析2012年5月至2013年3月18例临床病理资料完整的口腔癌患者的PET/CT(采用18F-脱氧葡萄糖作为示踪剂)影像资料,总结其病灶部位、形态、大小、强化特征、最大标准摄取值(SUVmax)和淋巴结转移情况。结果本组18例口腔癌患者中,原发病灶6例,可疑复发12例,PET/CT检查均能显示原发病灶大小、形态、周围组织侵犯、淋巴结转移情况,复发患者能准确显示复发病灶的部位、大小及淋巴结转移情况。结论 PET/CT能清楚显示口腔癌病灶的发生部位、形态、大小、累及范围及转移情况,能够准确区分复发患者中癌灶和术后治疗的纤维、瘢痕组织,可为口腔癌诊断和治疗提供准确的影像学依据。
