摘　　要：目的探讨在胸部ＣＴ图像上应用ＡＴＳ淋巴结分组方法。方法１０例患者（淋巴瘤５例，结节病２例，转移性淋巴肿３例）均有胸部ＣＴ扫描。所见的胸内淋巴结用ＡＴＳ方法进行分组。结果应用ＡＴＳ淋巴结分组法在胸部ＣＴ上划分６个区域。（１）第６颈椎上缘至肺尖区域包括１Ｒ／Ｌ组；（２）肺尖至主动脉弓上缘区域包括２Ｒ／Ｌ和６组；（３）主动脉弓上缘至隆突区域包括４Ｒ／Ｌ、５、６和１０Ｒ组；（４）隆突下方３ｃｍ以内区域包括７和１０Ｒ／Ｌ组；（５）隆突下３ｃｍ至横膈上区域包括８Ｒ／Ｌ和１４Ｒ／Ｌ组；（６）两肺上叶支气管以远的肺内淋巴结为１１Ｒ／Ｌ组。结论６个标志区域的划分，使ＡＴＳ淋巴结分组方法在胸部ＣＴ中的应用更简便、实用。Objective To assess the usefulness of the classification developed by the American Thracic Society (ATS) in the grouping of thoracic lymph nodes on CT scan. Methods Ten patients suffered from lymphoma (5 cases), sarcoidosis (2 cases) and metastatic lymphadenopathy (3 cases) were examinated with CT. The intrathoracic lymph nodes were grouped according to the ATS nodal classification.Results Six areas were divided on the CT scans: (1) between the upper margin of the sixth cervical vertebra and the pulmonary apex, including nodes in group 1R/L; (2) between the pulmonary apex and the uppper margin of the aortic arch, including nodes in group 2R/L and 6; (3) between the upper margin of aortic arch and the carina, including nodes in group 4R/L, 5, 6 and 10R; (4) within 3 cm below carina, including nodes in group 7 and 10R/L; (5) between 3 cm from subcarina and the top of diaphragm, including nodes in group 8R/L and 14R/L; (6) intrapulmonary area, distal to the upper lobe bronchi, including nodes in group 11R/L. Conclusion The division of lymph nodes into six areas on CT scan makes the ATS lymph node classification more easily applicable.
