摘要 目的探讨18F-FDG-PET/CT融合显像对头颈癌颈淋巴结转移的诊断价值。方法对照颈淋巴结清扫术后病理结果,回顾性对比分析20例头颈癌患者颈部PET、CT及PET/CT资料。结果对颈淋巴结转移癌的诊断敏感性、特异性及准确度,PET为92·3%、85·7%、90·0%,CT为77·0%、57·1%、70·0%,PET/CT为92·3%、100%、95·0%,PET/CT的诊断准确度显著高于CT(P<0·05)、略优于PRT;13例鼻咽癌放疗后患者,CT诊断正确7例,PRT/CT诊断正确12例;7例N0病例颈淋巴结清扫术后病理证实4例存在淋巴结转移,术前PET/CT均诊断正确。结论18F-FDG-PET/CT融合显像对颈淋巴结转移癌的诊断价值优于单独的PET及CT,尤其是对于治疗后的病例,其诊断优势更加突出,有望作为是否需行颈淋巴结清扫术的指征。
