pulmonary lobule

基本解释

However, these structures are the landmark to identify the secondary pulmonary lobule on HRCT images.
然而，小叶间隔、小叶肺动脉是HRCT图上认识次级肺小叶的标志。
The secondary pulmonary lobule has a polyhedral shape and is the smallest discrete portion of lung that is surrounded by connective tissue septae (interlobular septae).
次级肺小叶呈多边形，是由结缔组织间隔（小叶间隔）包绕的肺组织最小的独立单元。
