Abstract The efficacy of the nonenhanced magnetic resonance angiography (MRA) technique known as fresh‐blood imaging (FBI), using electrocardiograph (ECG)‐triggered 3D half‐Fourier fast spin‐echo (FSE), was evaluated for the detection and characterization of aortic diseases. Seventy‐five consecutive patients with aortic disease underwent the FBI examination on a 1.5‐T clinical imager. The results showed that the FBI technique permits clear visualization of aortic diseases, and the vessel branches and their relationship, which provides valuable information. Therefore, the nonenhanced FBI technique is appropriate to use for screening purposes. J. Magn. Reson. Imaging 2001;14:113–120. © 2001 Wiley‐Liss, Inc.
