摘　　要：目的:探讨PET/CT检查定性诊断头颈部肿大淋巴结的应用价值。材料和方法:于2006-06～2008-10对38例头颈部淋巴结肿大的患者行全身18氟-脱氧葡萄糖(FDG)PET/CT检查,测取相应淋巴结的平均标准摄取值(SUVmean)和颈部正常组织的SUV(SUVneck)。所有恶性淋巴结全部得到病理确诊。结果:30例恶性肿瘤患者中,35个肿大淋巴结的SUVmean高于相应的颈部正常组织SUVneck;5例7个良性肿大淋巴结未见显影,3例4个良性肿大淋巴结显影。PET对头颈部淋巴结肿大定性诊断准确率高于颈部超声与CT、MRI检查(P<0.001)。结论:对于头颈部淋巴结肿大的患者,PET/CT检查是一种有效的定性诊断途径。Purpose To assess the value of 2-（fluorine-18）fluroro-2-deoxy-D-glucose（FDG）-PET/CT on the diagnosis of cervical lymphadenopathy.Materials and Methods FDG-PET/CT was performed in 38 patients with cervical lymphadenopathy from June 2006 to October 2008.The standard uptake value（SUV）of abdominal lymph nodes（SUVmean）and SUV of normal cervical lymph nodes（SUVneck）were measured.All malignant lymph nodes were pathologically proved.Results 35 enlarged lymph nodes detected in 30 patients demonstrated higher SUV than normal neck tissue.7 benign lymph nodes were not visualized and 4 benign ones were visualized.The accuracy of PET/CT in indicating the malignant lymph nodes was higher than that of ultrasonography,CT and MRI（P〈0.001）.Conclusion PET/CT is an effective tool in differentiating malignant lymph nodes from benign ones for patitents with lymphadenopathy.
