Dynamic three-dimensional magnetic resonance abdominal angiography and perfusion: implementation and preliminary experience

J Magn Reson Imaging. 2000 Feb;11(2):201-7. doi: 10.1002/(sici)1522-2586(200002)11:2<201::aid-jmri19>3.0.co;2-4.

Abstract

Implementation of and preliminary experience with an ultra-fast partial-Fourier radiofrequency (RF) spoiled gradient-echo sequence for gadolinium-enhanced imaging are presented. Three-dimensional angiograms can be acquired in less than 6 seconds. Repetition of the acquisition allows the three-dimensional visualization of several distinct vascular phases. Feasibility is demonstrated in three healthy volunteers. The trade-offs among spatial resolution, temporal resolution, and spatial coverage as well as the technical aspects of gadolinium-enhanced pulse sequences are discussed.
