肺门高度率(HHR)是用数字来表示,是观察和分析肺门位置正常与否的一种方法。肺体积改变,肺下和膈下病变均可产生HHR异常。因此,对肺门高度率的研究颇为重要。对于肺门形态、大小和结构的研究国内外报道甚多,而HHR的资料国内尚未见报道。本文对200例正常胸片HHR进行分析,并讨论HHR在胸部疾病诊断中的意义。一、材料来原和方法本文随意选择体检而照胸片无异常发现,又无心肺病史的正常人200例。所有胸片均为深吸气立位相,焦片距180cm。右膈在第5～
Hirth height (HHR) is represented by numbers, which is a way to observe and analyze the normal position of hilar position. Changes in lung volume, sub- and sub-hypoxia lesions can produce abnormal HHR. Therefore, the study of the hilum height rate is quite important. There are many domestic and international reports on hilar morphology, size, and structure, and the data on HHR have not been reported in China. This article will analyze 200 cases of normal chest X-ray HHR and discuss the significance of HHR in the diagnosis of chest diseases. First, the material to the original and method This article randomly selected physical examination and chest film without abnormal findings, and no history of normal heart and lung 200 cases. All chest radiographs are deep inhalation standing phase, focal distance 180cm. The right hand is in the 5th~
