Abstract
The recent advent of newer multidetector computer tomography (MDCT) scanners has dramatically changed the role of magnetic resonance imaging (MRI) in the evaluation of the abdominal aorta and its peripheral branches, due to its faster acquisition times, higher spatial resolution allowing to obtain submillimetric sections with voxel isotropy, greater technical simplicity, wider availability, and lower overall cost. However, lack of ionizing radiation and of intravenous administration of iodinated contrast material remain substantial advantages of MRI over MDCT, that make it the technique of choice for young patients and individuals with high serum creatinine values. Moreover, for the assessment of renal arteries MRI offers not only adequate anatomical detail but, and more importantly, is also able to provide quantitative data relative to renal blood flow, as well as to yield functional information about the parenchymal effect of a vascular stenosis by means of phase contrast and perfusion techniques, respectively. In this particular concern, MRI may be successfully proposed as a novel noninvasive tool for functional evaluation of the kidneys.
