Ultrasonography of the diaphragmatic crura.
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.
