摘要
参照美国胸科协会的纵隔淋巴结分区法,在38具正常成人尸体上观察了纵隔各区淋巴结的数目、形态以及各区最大淋巴结的大小和方位。各区淋巴结的数目不等,形态各异,以1～3个椭圆形淋巴结常见。测量了各区最大淋巴结的长、宽、厚径。各区淋巴结大小不等,其中7区最大,5区次之。经统计学分析确定了正常纵隔各区淋巴结各径的最大值标准。讨论了淋巴结不同方位对 CT 横扫时淋巴结大小测量的影响。
The number and shape of mediastinal lymph nodes as well as the size and orientation of thelargest ones in different regions were observed on 38 normal adult cadavers according to thezonation definitions by American Thoracic Society.The number and shape of the lymph nodesvary with different regions,but were usually seen as 1-3 ellipsical ones in each region.It was al-so found that the size of the lymph nodes changed in different regions and the largest ones warein region 7 and region 5.The statistic mean maximum of the normal mediastinal lymph nodes insize in different regions were determined.The influence of orientation of lymph nodes on trans-verse scanning CT imaging was discussed.
