摘要 目的比较18F-氟代脱氧葡萄糖(FDG)-正电子发射计算机断层显像(PET-CT)和磁共振成像(MRI)、CT在鼻咽癌患者局部肿瘤中检测的差异。方法老年原发鼻咽癌患者均按照同一固定的体位完成PET-CT和MRI、CT的扫描检查。比较三种检查方案对于肿瘤检查结果的差异。结果 PET-CT的咽后淋巴结转移检出率显著低于CT(χ2=4.656,P=0.031)和MRI(χ2=9.905,P=0.002);横径为0.4~1.0 cm的咽后淋巴结CT、MRI、PET-CT检出率分别为64.5%、63.9%、25.0%;1.0~2.0 cm分别为25.8%、22.2%、40.0%;≥2.0 cm分别为9.7%、13.9%、35.0%。结论PET-CT检测鼻咽癌的局部肿瘤侵犯较CT、MRI更为优秀,但对于直径较小的肿瘤病灶,PET-CT的检出率相对较低。
