目的:为隆嵴下间隙内病变的临床影像学诊断提供解剖学依据.方法:在32具成年整尸(男、女各半)的胸部连续横、矢和冠状断层上,观测了隆嵴下间隙.结果:此间隙位于气管权与左心房之间,显示于气管隆嵴平面至右肺动脉平面,高度为18.6±3.3mm,厚度为12.1±1.4mm,该间隙内较恒定地出现气管支气管淋巴结,其短横径为7.1±1.1mm.结论:在断层上可清晰显示隆嵴下间隙,以满足临床影像学诊断的需要.
Objective: To provide anatomical basis for the clinical imaging diagnosis of the lesions in the subcostal crest.Methods: Thirty-two adult male and female halves of the chest continuous transverse, sagittal and coronal sections were observed under the ridges The gap was located between the tracheal right and the left atrium and was shown on the plane of the trachea ridge to the plane of the right pulmonary artery with a height of 18.6 ± 3.3 mm and a thickness of 12.1 ± 1.4 mm with a more constant tracheobronchial lymph node , The short diameter of 7.1 ± 1.1mm.Conclusion: The gap under the ridge can be clearly displayed on the fault to meet the needs of clinical imaging diagnosis.
