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。
Objective To analyze the characteristics of positron emission tomography (PET) and computed tomography (CT) in oral cancer and to explore the value of PET / CT in the diagnosis of oral cancer. Methods The data of PET / CT (18F-deoxyglucose as tracer) in 18 cases of oral cancer patients with complete clinical and pathological data from May 2012 to March 2013 were retrospectively analyzed. The location, shape, size, enhancement Characteristics, maximum standard uptake (SUVmax) and lymph node metastases. Results Of the 18 patients with oral cancer, there were 6 primary lesions and 12 suspicious ones. PET / CT examination showed the size, shape, surrounding tissue invasion and lymph node metastasis of patients with recurrent tumors The location, size and lymph node metastasis. Conclusion PET / CT can clearly show the location, shape, size, extent and metastasis of oral cancer lesions, and can accurately distinguish the cancerous lesions in the recurrence patients and the postoperative treatment of fibrous and scar tissue, which can provide the diagnosis and treatment of oral cancer Accurate imaging basis.
