What is the role of magnetic resonance angiography (MRA) in patients with suspected abdominal angina?
In patients with suspected abdominal angina, MRA may be helpful in those with a severe iodine allergy. Good correlation with CT angiography has been demonstrated, and three-dimensional reconstruction allows for visualization of splanchnic orifices.
Additionally, in patients with chronic kidney disease or impaired kidney function, gadolinium may not cause the contrast induced nephropathy seen with iodine. It can, however, uncommonly lead to nephrogenic systemic fibrosis, which is an irreversible condition.
