On a transverse axial slice of the abdomen the posterior abdominal wall is composed of the lumbar spine and the lumbar muscles with their different fat planes. The psoas muscles, intimately related to the vertebral body, assume a more symmetric and round form as the slices proceed from the cranium caudad. The great vessels are situated immediately before the vertebral bodies. The aorta is visible as a circular structure, which, on the upper abdominal slices, cannot be distinguished from the medial crura of the diaphragms. On all other slices the aorta is seen distinctly, even the aorto-iliac bifurcation. Below the renal arteries, however, the caliber of the visualized abdominal aorta progressively diminishes.
