ABSTRACT
Magnetic resonance can be performed to assess the anatomical structure of the kidney (e.g. single kidney, horseshoe kidney, transplant kidney) and for the presence of any mass (e.g. renal neoplasm, adrenal adenoma). With gadolinium-enhanced magnetic resonance angiography (MRA), it is now possible to accurately image the renal arteries and renal veins. In addition, renal artery stenosis can be confirmed with the use of phase-contrast velocity mapping perpendicular to the artery, before and after the stenosis.
