ABSTRACT:
A method for acquiring spatial and velocity image data for three dimensional magnetic resonance angiography simultaneously by using a stepped bipolar gradient pulse in which the zeroth gradient moment is nulled by the second lobe of the pulse to provide a second echo which encodes velocity information, and spatial information is readout following the first lobe of the bipolar pulse. The preferred embodiment of the invention utilizes a multiple overlapping thin slab acquisition technique which makes possible high quality images for both spatial and velocity signals.
