摘要

In the 1980s and early 1990s, time-of-flight and phase contrast magnetic resonance (MR) techniques were considered the state of the art methods of MR angiography until the advent of contrast-enhanced MR angiography (CE-MRA) introduced in the early to mid 1990s (1). Many consider CE-MRA MRI to be an appropriate "one-stop shop" (2) imaging exam in the evaluation of a renal donor (3-5).There has been a renewed interest in noncontrast-enhanced (NCE) MRA techniques for several reasons. First, if one could provide a comprehensive MR exam without having to administer gadolinium, the study could be completed with less cost (6). Second, a small but true risk of acute allergic reaction to gadolinium could be avoided by performing a nonenhanced exam (7). Finally, gadolinium administration has been associated with the development of nephrogenic systemic fibrosis, especially in those patients with reduced renal function (8).
