In roentgenograms of the chest, it was observed that there was an increase in the difference between the right and left domes of the diaphragm in the right lateral views when compared with the difference present in the posteroanterior views. A difference of 3-5 cm in posteroanterior views and 5-0 cm in the right lateral views, could be considered normal values. The greater difference in the levels of the domes of the diaphragm in the right lateral views was confirmed in a study using hepatic models. Factors responsible for this radiological distortion have been outlined and the clinical significance of this phenomenon in respect to elevation of the right dome of the diaphragm has been discussed.
在胸部X光片中观察到，与后前位相比，右侧位膈左右穹窿之间的差异有所增加。后前位差异为3 - 5厘米，右侧位差异为5 - 0厘米，可视为正常值。在一项使用肝脏模型的研究中证实了右侧位膈穹窿水平差异更大。已经概述了造成这种放射学扭曲的因素，并讨论了这种现象在膈右侧穹窿升高方面的临床意义。
