Implementation of and preliminary experience with an ultra-fast partial-Fou
rier radiofrequency (RF) spoiled gradient-echo sequence for gadolinium-enha
nced imaging are presented. Three-dimensional angiograms can be acquired in
less than 6 seconds. Repetition of the acquisition allows the three-dimens
ional. visualization of several distinct vascular phases. Feasibility is de
monstrated in three healthy volunteers. The trade-offs among spatial resolu
tion, temporal resolution, and spatial coverage as well as the technical as
pects of gadolinium-enhanced pulse sequences are discussed. (C) 2000 Wiley-
