Three-dimensional contrast-enhanced moving-bed infusion-tracking (MoBI-Track) peripheral MR angiography with flexible choice of imaging parameters for each field of view

A technique to image peripheral arteries with flexible choice of scan param eters for separate stations was developed based on moving-bed single-bolus three-dimensional gradient-recalled echo magnetic resonance angiography, A volunteer study yielded higher signal- and contrast-to-noise ratios, less v enous enhancement, and better subjective Interpretability compared with ima ging with fixed parameters for each station. Additionally, sig patients wer e imaged to test the feasibility of the new method in a clinical setting. I maging peripheral arteries with the new technique in volunteers yielded bet ter image quality and is feasible for patients, (C) 2000 Wiley-Liss, Inc.
