Misinterpretation of the diaphragmatic crura on axial computed tomography images is a recognized pitfall in diagnosis. The right diaphragmatic crus is generally longer and thicker than the left. The authors observed a case in which the left crus was thicker than the right, causing diagnostic difficulty. Obtaining scans at full expiration and full inspiration clarified the situation. Confirmation of respiratory variation in crural thickness was obtained in ten patients. The crura increased in thickness on inspiration, compared with the size on expiration.
在轴向计算机断层扫描图像上对膈脚的错误解读是诊断中公认的一个陷阱。右侧膈脚通常比左侧更长更厚。作者观察到一例左侧膈脚比右侧厚的病例，这导致了诊断困难。在完全呼气和完全吸气时进行扫描使情况得以澄清。在10名患者中证实了膈脚厚度的呼吸变化。与呼气时的尺寸相比，膈脚在吸气时厚度增加。
