Introduction
Three-dimensional (3D) gadolinium magnetic resonance angiography (MRA) has been established as a safe and reliable technique for detection and grading of renal artery stenosis. Due to the lack of need for nephrotoxic contrast agents and ionizing radiation, this technique is particularly attractive for patients with kidney transplants or those with renal failure. With the introduction of high performance MR systems with fewer upfront costs and cheaper maintenance, the technique has gained widespread use even in community hospitals and private practices.
Despite its overall significant role in the diagnostic work-up of patients with renal artery stenosis, the technique currently faces several new challenges to be overcome. Although a reproducible quality of the 3D gadolinium MRA images with a high level of accuracy has been well documented in numerous studies, doubts have been cast on the results recently by new data from multicentre trials [1,2]. These studies question
New technical developments: high resolution renal MRA and extended anatomic coverage
Feasibility of a comprehensive morphological and functional evaluation: experience of 5 years
Impact on patient management
