摘要
目的：本研究旨在以PET/CT FDG显像为手段，探讨老年患者肺门、纵隔淋巴结代谢变化特点及其在鉴别诊断肺门纵隔淋巴结良恶性中的临床价值。材料和方法：≥60岁的FDG PET/CT显像受检者61例纳入研究。根据肺门和纵隔高代谢淋巴结（HML）分布状况，将受检者分为4组：无HML者为A组、双侧HML者为B组、肺部占位性病灶同侧HML高代谢者为C组、其他HML者为D组。结果：35/61例（57.4%）老年受检者出现高代谢肺门和纵隔淋巴结。61例受检者中，分别有7例和54例发生和没发生肺门和纵隔淋巴结转移。A、B、C、D组受检者肺门和纵隔淋巴结转移分别为0、3、4和0例，非淋巴结转移分别为26、13、2和13例，χ2为23.9，P<0.001。结论：老年人肺门和纵隔高代谢淋巴结发生率高，肺门和纵隔高代谢淋巴结分布形态对于判断是否为恶性病变累及有帮助。
Abstract
Objective: To evaluate the clinical value of the distribution types of the hilar and mediastinal high metabolic lymph nodes in the aged by PET/CT image. Materials and Methods: Sixty-one patients ≥60 years old underwent FDG PET/CT images. According to the distribution of the hilar and mediastinal high metabolic lymph nodes(HML), all patients were divided into 4 groups: patients without HML as group A, with bilateral HML as group B, with HML at the same side of the lung nodule or mass as group C, other patients as group D. Results: Of the 61 patients, 35(57.4%) patients had HML, 7 patients and 54 patients with and without hilar and mediastinal metastatic lymph nodes respectively. In group A, B, C and D, there were 0, 3, 4 and 0 patients with hilar and mediastinal metastatic lymph nodes respectively, and there were 26, 13, 2 and 13 patients without hilar and mediastinal metastatic lymph nodes respectively, P<0.001. Conclusion: The inccident rate of hilar and mediastinal high metabolic lymph nodes is high. The distribution types of HML is useful to find the malignant HML from the benign ones.
