The diaphragmatic crura are being recognized with increasing frequency on routine sonograms. In a study of 100 random patients the right crus was seen in parasagittal scans in 50% of patients and in transverse scans in approximately 90%. The left crus was not specifically identified on parasagittal scans, but was visible in about 50% of patients on transverse scans. Longitudinal coronal approaches can significantly improve visualization of the crura.
在常规超声检查中，膈肌脚被识别出的频率越来越高。在一项对100名随机患者的研究中，在矢状旁扫描中，50%的患者可见右侧膈肌脚，在横断扫描中，约90%的患者可见。在矢状旁扫描中未明确识别出左侧膈肌脚，但在横断扫描中约50%的患者可见。纵向冠状面扫查可显著改善膈肌脚的可视化。
