3D CE MRA is capable of displaying the main visceral vessels with excellent diagnostic accuracy. However, the spatial resolution achievable with selective catheter angiography remains superior for

smaller branch vessels. Accordingly, current clinical applications of 3D CE MRA in the splanchnic circulation focus on clinical situations that require assessment of the proximal celiac axis and SMA. Typical pathologies are mesenteric ischemia, visceral artery aneurysms, tumor encasement, anatomic variations (see sub-chapter), and pre/post liver transplantation.
