自1925年Baum和Black二氏著文报导使用前弓位胸部X线摄影,检查肺部隐蔽病灶的实际价值,如小面积的肺尖病灶和肺尖空洞;Fleischner氏利用此种摄影法检查叶间渗出液以来,有些人还用它来检查右肺中叶萎缩和右室流出道及肺动脉弓的情况。到目前为止,关于前弓位胸部X线摄影检查肺部隐蔽病灶的文献报告逐渐增加,在国内各医院应用这种X线摄影方法,也日趋广泛。我院从1954年1月至1957年10月在后前位像136张中,同时拍照了前弓位像,其中108例发现有明显病灶或空洞存在,约占79.4％。在我们应用的过程中,感到前弓位在检查肺尖病灶、肺尖空洞、叶间胸膜炎上,非常必要;同时在确定病灶部位上也有价值。
Since Baum and Black’s writings in 1925 reported the use of anteroposterior chest radiography to examine the true value of subtle lung lesions such as small area apical foci and apical cavities; Fleischner’s method used this method to examine leaves Since exudate, some people also use it to check the right middle lobe atrophy and right ventricular outflow tract and pulmonary artery arch situation. Up to now, there is a growing number of reports on the detection of hidden lesions in the lungs by chest X-ray photography of the anterior arch. This method of X-ray photography is widely used in various hospitals in China. In our hospital, from January 1954 to October 1957, there were 136 pre-position images, while the anterior arch images were taken at the same time. Among them, 108 cases showed obvious lesions or voids, accounting for 79.4%. In the course of our application, it is very necessary to feel the anterior vertebral axis in examining the tip of the apical foci, apical cavity, and pleuritis in the intervertebral space. Meanwhile, it is also valuable in determining the lesion site.
