Which crus of the diaphragm is visualized anterior to the aorta above the level of the celiac artery?

The left crus of the diaphragm is positioned to the left side of the aorta and is typically visualized anterior to it above the level of the celiac artery. This anatomical configuration occurs because the left crus extends upward and forward, creating a relationship where it can be seen anteriorly in imaging studies.

The aorta arises from the heart and descends vertically through the thorax into the abdomen, while the celiac trunk branches off at approximately the level of T12. The left crus being anterior to the aorta in this region is a distinct feature that differentiates it from the right crus, which is generally posterior to the aorta at this level. Understanding the spatial orientation of the crura relative to the aorta is crucial for interpreting abdominal imaging and performing procedures.
