【摘要】： 目的：通过解剖学观测和MSCT影像学研究，探讨正常纵隔淋巴结短径的MSCT正常值范围。材料和方法：参照改良的ATS淋巴结分布图，对经严格选择的38例成人尸体标本和70例无纵隔淋巴结肿大者分别行解剖学观测和MSCT研究，并由3位在有经验的放射科医师盲法观察影像资料。结果：1．解剖学观测结果：38例成人尸体标本共观察到824个纵隔淋巴结。各区淋巴结的形态以圆形和类圆形为主，约占76％，5区和7区其他形状的淋巴结相对较多。各区最大淋巴结的方位多呈竖位，但5区多呈横位。2．MSCT观测结果：70例病例一共测得纵隔淋巴结1521个，平均每例21.73个，平均大小为3.54mm±1.37mmSD。不同区域淋巴结的数目和大小各不相同。2R区淋巴结数目多于2L区(P＜0.05)，4区淋巴结数目明显多于2区(P＜0.01)，，4R和4L区淋巴结的数目没有显著性差别(P=0.785)。2R区淋巴结明显大于2L区(P=0.01)，10R区淋巴结明显大于10L区(P＜0.01)，4区淋巴结明显大于2区(P＜0.01)，7区淋巴结明显大于4区(P＜0.01)。结论：纵隔各区淋巴结的大小和数目不同；正常纵隔淋巴结短径的MSCT标准是：7和10R区≤8mm，2L、6和10L区≤5mm，其余5个区均≤6mm。
[Abstract]:Objective: to study the normal range of MSCT of mediastinal lymph node by anatomical observation and MSCT imaging study. Materials and methods: 38 adult cadavers and 70 cases without mediastinal lymphadenopathy were studied by anatomical observation and MSCT study with reference to the modified ATS lymph node distribution. The imaging data were observed by 3 experienced radiologists. The result is 1: 1. Anatomical results: a total of 824 mediastinal lymph nodes were observed in 38 adult cadavers. The shape of lymph nodes in each region was mainly round and round, accounting for more lymph nodes of other shapes in area 765 and area 7. Most of the largest lymph nodes in each region were vertical, but most of the 5 regions were horizontal. 2. The results of MSCT showed that 1521 mediastinal lymph nodes were detected in 70 cases with an average of 21.73 per case, and the average size was 3.54mm 卤1.37 mm SD. The number and size of lymph nodes in different regions were different. The number of lymph nodes in region 2L was more than that in region 2L (P < 0.05P < 0.05). There was no significant difference in the number of lymph nodes between region 4R and region 4L. The lymph nodes in region P0. 785. 2R were significantly larger than those in region 2L (P < 0. 0110R), and there was no significant difference in the number of lymph nodes between the two regions (P < 0. 785, P < 0. 0110R). The lymph nodes in the region were significantly larger than those in the region 10 L (P < 0.01) and the lymph nodes in region 4 (P < 0.01) than those in the region 2 (P < 0.01) and the lymph nodes in region 7 were significantly larger than those in the fourth region (P < 0.01). Conclusion: the size and number of lymph nodes in mediastinal regions are different, and the MSCT criteria for the short diameter of normal mediastinal lymph nodes are 鈮
