To determine the ability of fast gradient-recalled echo (GRE), breath-hold magnetic resonance imaging (MRI) to depict all regions of the diaphragm, 13 volunteers were scanned in coronal and sagittal planes. The central to anterior left hemidiaphragm and the posterior lumbar portions were each demonstrated in 12 subjects (92%). The crura were visible crossing anterior to the aorta in the sagittal plane in eight subjects (62%) and in the coronal plane in six subjects (46%). In the sagittal plane, the right crus was evident in eight subjects (62%). Muscular portions of the diaphragm in contact with the liver or body wall were less frequently discernible, and the central tendon could not be confidently resolved. Several artifacts occurred that interfered with visualization of the diaphragm. These observations indicate that many regions of the diaphragm can be seen with fast GRE, breath-hold MRI, but there are some limitations in depicting the diaphragm in its entirety.
